anima® 5.6
FREE RENDER NODES
The new version does not require a license for the Render Node installation mode and has no limit on the number of machines where render nodes can be installed.
Which means that, from version anima® 5.6.0 onwards, everybody can render anima® content without limitations for free!
anima® 5.5
NEW ANIMABLE PLAYBACK
Now it is possible to animate with keyframes the Time offset value in 3ds Max:
This allows modifying the playback of the simulation at will, using standard animation keys and curves, which hugely expands the possibilities for creating non linear and innovative time effects:
STATIC MOTION BLUR EFFECT
The same Time offset animable parameter can be used with an inverse linear animation curve and activating the Motion Blur of the camera in V-Ray to create an stunning Static Motion Blur effect:
anima® 5.0
NEW 4D WALKING MODELS
Now you will be able to take profit from the incredible appeal and realism of the 4D technology and extend it even more because, in this new version, we have extended our industry-acclaimed 4D Digital Human models to give them the ability to walk through your scenes.
We have created a new default group of models in our metropoly® library named “4D Walking“, and renamed the previous “4D” section to “4D Animated“. All the models included in this new 4D Walking group can be used to populate the paths created with the new 4D path tool (more info below).
NEW 4D PATH TOOL
The new 4D path tool is the tool that creates the new paths compatible with the 4D Walking models. The new 4D paths can be drawn directly using the dedicated 4D path tool that is available in the toolbar, or can also be used by just dropping a 4D Walking model into the 3D viewport.
It works almost the same as the standard Path tool but has some important differences that are derived from the limitations that the 4D technology has. For example, there is no “generate” button for these paths, so you must place the models manually by dropping them wherever you want on the path. Also, they have limited interaction capabilities with the environment and will be ignored by the other crowd tools like the Avoid and Socialization areas or the Traffic lights.
Keep in mind that the 4D models are incredibly realistic due to the huge detail that the volumetric scanners are capable to capture in animated geometries and textures. However, this also makes these models heavier and may have a great impact on the overall performance, especially in real-time environments (Unreal Engine®), so use them wisely.
NEW RUN / WALK “IN PLACE” OPTION
One of the options available on the new 4D walking models is the ability to make them move “in place,” without applying any translation. That has been a feature much requested by users who often populate gyms with treadmills.
Now you can do that by dropping a 4D walking model outside its path and then activating the “move in place” option.
NEW NEURAL CROWDS
The Rigged models are now driven by our new Neural Crowd simulation system which is based on a new technology that uses Artificial Intelligence based on neural networks to achieve better realism and appeal in all situations.
NEW PATH LOOPS (Closed Paths)
Thanks to the new incredible capabilities of the new neural crowd simulation engine, we have been able to add one of the most requested features by our users, which is the possibility of creating closed paths, commonly referred to as loops.
Now, when creating a path, after a few points are made, if you click on the initial point of the path and it will automatically become a loop (closed path). Also, it is possible to close a path after it is created, by simply dragging one extreme of the path over the other extreme.
NEW anima® DROP
The anima® Drop panel has been greatly improved to become a powerful autonomous tool. Now you can download models directly from the panel (no need to open the anima® Designer to download anymore).
Also, we added support for all the types of models that don’t require an animation engine (Ready-Posed, Ambient, and 4D Animated), so you now can add them directly from the anima® Drop panel to your 3dsMax® and Cinema4D® scenes.
One of the benefits of using the anima® Drop panel is that you can manipulate the transforms of the actors individually, using the standard tools of your 3D application.
This opens the possibility of changing the position, rotation, and scale of each actor more comfortably using the tools and the interface of your own 3D application. But more importantly, this also allows you to use a whole new range of tools from your own 3D software related to the manipulation of those transforms, like for example linking actors to animated objects of your scene (very useful on vehicles or elevators), or getting a mirror animated version of the 4D models.
NEW SCENE HELPERS
The new version introduces an important change in the structure of the imported scenes into 3dsMax® and Cinema4D®. Now there will be a new anima® helper per each anima® scene that is imported, and all the actors from that scene will be placed in relation to the transform of that scene helper.
It always has been possible to apply position and rotation transform modifications to the anima® actors directly from the plugins by using the “unlock transform” parameter. But now, you will be able to modify also the scale and do it on each one of your scenes, independently.
Although this seems to be a simple change, it has huge implications and opens a whole new range of possibilities that were not possible in previous versions of anima®. For example, now you can make one of the scenes follow the animation of a vehicle while the other scene keeps its relative position. This would be a typical situation in a project that takes place in a train station. You now can create 2 different scenes, one populating the train and another one populating the people on the platform, and then attach the scene helper from the Train Scene and make it follow the same animation that the actual Train object has in your 3D scene.
Also, with the new scene helpers, you take profit from the free transform manipulation possibilities that the new scene helpers bring by scaling or even mirroring entire scenes.
NEW PANELS TOGGLE
The title bar of the main anima® Designer application has been updated to make it simpler and clearer.
All the panel buttons have now been grouped into a single Panel Toggle drop-down, where you will find a description of each panel and a little dot on the left side, depending on its shown or hidden state. This way it is easier and quicker to find the panel you need and its current state.
NEW VISUAL SCALE PARAMETER
Now you can change the visual scale of all the actors directly from the viewport by just selecting them and modifying the new SCALE parameter from the properties panel.
The modifications applied to this parameter will not affect the simulation engine, but they will have an effect on the visual perception of the geometry of the model. This means that you can end up having sliding feet in the simulations of Rigged or 4D walking models that have been scaled, so use it carefully.
NEW DESIGN FOR THE “RESOURCE CACHE”
The Resource Cache was introduced in version 4.5 and was designed to make it easier for the users to manage and share anima® projects with other people and services (like online render farms) without having to deal with the management of the models that were used on each project.
However, when anima® was used in shared networks, the initial design of the resource cache had workflow issues (see the “Missing Actor” section of this article) due to the lock that the Windows OS creates when the stream models (4D models) were read from other machines of that network. As a result of that, working on new scenes while other machines (i.e. render nodes) were reading another scene of that same project could lead to end up having “Missing Actors” in the renders.
The problem has been completely solved in this new version. We the new design, it is not a problem anymore to work on new scenes while reading or rendering the finished ones with other machines from your network.
Also, from now on, total consistency is guaranteed between the resources to which the Workstations and the Render Nodes (or your Render Farms) have access. Therefore, in the unlikely situation that you might have a missing resource in the resource cache of the project (for any unknown reason), that problem will be visible right away from the anima® plugins of the Workstations and the Render Nodes at the same time, in all cases, because now both will be accessing the same pool of resources.
anima® 4.5
NEW SUBSCRIPTION LICENSE: anima® ALL
This update introduces for the first time in the 3D CG industry the very concept that has already been a revolution in the industries of Music, Broadcasting, and VideoGames: unlimited access to content based on a subscription fee.
Let’s think about what this actually means for a minute. Our current library has already more than 1.500 models of people, and it grows steadily every month. Having unlimited access to such a huge amount of content means that you won’t need to spend more resources purchasing models in advance, without ever knowing for sure if you will actually have the chance to use them on your next project.
That means anima® ALL gives you everything you need to populate your scenes, so you can focus on the most important thing: your project.
SEAMLESS AUTOMATIC DOWNLOAD
You will always see all your models available in your library, it does not matter anymore if the model is already in your Purchases folder or not. You can always just drop the model to the scene and anima® will take care of the rest.
This new feature is even more valuable when you own a Subscription because it gives you instant access to ALL the models of the metropoly® library. Anytime, anywhere, you can just focus on finding the model that best fits your scene and drop it in there.
IMPROVED LIBRARY SEARCH
All the libraries in anima® have a search field that appears when you hover the mouse in the title bar of the panel. If you start typing something there, the auto-complete feature will show you a list of the terms that you might want to write, and you can select any of them using the Down Arrow key.
On this version, this search tool has been improved to support multiple additive terms. This new simple but very powerful feature appears as a direct consequence of having access to a huge number of models.
SIMPLIFIED RENDER RESOURCE MANAGEMENT
New highly optimized cache that collects all the resources used on any of the scenes of your project and stores them directly inside your main anima® project folder. That means that it will be no more dependencies towards your Purchases folder location or contents.
This allows both, the Nodes and the Plugins, to load any anima® project by just having access to the anima® project folder. Also, it will freeze those assets and keep them as they were at the moment when the project was saved for the last time
UPDATED QUICK DROP PANEL
We have completely redesigned the Quick Drop Panel to make it more seamlessly compatible with the projects made with anima®. It is not a standard anima® project yet but a hybrid that keeps the simplicity of the older Drop but makes it compatible with the anima® resources while keeping the possibility of directly dropping the models into your 3D application.
Now the actors dropped are not disconnected from the plugin anymore, so you can keep some of the benefits of the models that before were only accessible from anima® standalone, such as direct access to all the texture variations, or the automatic adaptation of the shaders to your current renderer.
To achieve that, behind the scenes, the plugin automatically creates a completely functional anima® project in your current 3D App scene directory. This opens a whole new set of possibilities that can be added in the future, like supporting more types of models or recreating a standard anima® scene that replicates the same distribution of models as in the main 3D App.
That said, currently, the only types of models supported are the same ones that were supported in previous versions: Ready-Posed and Ambient (which are dropped as static).
anima® 4.1
anima®
- The biggest improvement comes from the addition of GPU video decoding for those with compatible NVIDIA GPUs. In supported systems, a new option will be visible from the preferences panel to choose between CPU or GPU video decoding. Choosing GPU decoding will give significant performance improvements when playing 4D actors in the anima viewport while reducing CPU usage overall.
- Many other tweaks have also been implemented to handle a larger number of 4D actors in the viewport at the same time without the need to turn them into boxes. If you want to try this out, make sure to increase the previous limit of visible 4D actors in the viewport’s graphics panel.
- A new LOD has also been implemented to improve playback from very far distances, which will be automatically applied when updating the 4D assets to their newer version.
- Simulation performance has been improved on scenes with large backgrounds. The internal collision tree has also been made more efficient, resulting in both a speed increase and a file size reduction for any anima project.
metropoly®
- The whole collection of 4D actors has been reprocessed to give a higher and more consistent level of quality. These assets are backward compatible with previous versions of anima, but most of their performance improvements will be available when updating anima to 4.1.0.
- The most notable change will be that the texture quality of these actors when being rendered by the anima Plugin will be higher than the current version.
3dsMax®, Maya® and Cinema4D® Plugins
- Added support for 3dsMax® 2022, Maya® 2022, and Cinema4D® R23.
- A new viewport setting has been added to either use colored or textured 4D actors. Colored actors update much faster, improve the responsiveness of the viewport when moving the time bar, and will still show up as fully textured in renders. We recommend using this new setting for a much smoother user experience when using 4D actors in these plugins.
- Reduced memory usage and increased performance when generating motion blur samples with 4D actors in 3DS Max.
Unreal Engine 4® Plugin
- Added support for Unreal Engine 4.26.
- This update also includes many optimizations to the Unreal Engine 4 plugin, making real-time playback of anima projects much more viable. First, LODs are now generated for all characters, resulting in many performance improvements when looking at large crowds of characters from a distance. Second, we’ve added direct transfer capabilities when using GPU decoding for the playback of 4D actors, resulting in some really big increases in real-time performance. For example, internal benchmarks have shown that scenes with up to 20 4D actors can go from around 20 FPS to 160 FPS in a system using a single GTX 1080, making these projects much more viable for projects that require high refresh rates. These performance improvements are available when using the D3D11 or D3D12 RHI. The Vulkan RHI will also have performance improvements, but no direct transfer is available at the moment. We encourage you to give this update a try if you were interested in having 4D actors in real-time scenarios.
anima® 4.0
NEW TYPES OF MODELS
- 4D Digital Humans: New actors capable of preserving all the details of the clothing and offer facial animations that provide unattainable realism using a new motion capture technology with a lossless compression while preserving all the detail of the source animated mesh.
- Ambient actors: Improved static models by adding them to a new automatic rig algorithm that generates subtle movements to simulate realistic idle animations on models that previously caught the eye for being absolutely static.

- Now you can bake animations at anytime. If the frames have not been cached yet then the caching will start at the moment you click the lock button.
- Improved responsiveness with large scenes due to an optimized way to handle tool editions that avoids bottlenecks and unneeded viewport updates.
IMPROVED ACTOR AND ANIMATION IMPORTER
- Improved compatibility with third party characters (iClone, RenderPeople, HumanAlloy and more…)
IMPROVED ACTOR LIBRARY
- Re-calibrated skin and material tones for all the actors available for anima®.
anima® 3.0
NEW UNREAL ENGINE 4 PLUGIN
- New Unreal Engine 4 Plugin! Import your anima scenes into Unreal Engine 4 easily with the new native support. Most of your favorite features from the 3DS Max and C4D Plugins have already been included!
- Added support for version 4.19 and 4.20.

IMPROVED USER INTERFACE
- Chairs, Squares, Escalators, Traffic Lights and Avoid Areas are now drawing tools instead of object templates! You can now find all of these objects and even more options on the left toolbar in the main editing view. You can also change your preferred drawing shape for these objects by clicking on the small arrow on top of them, allowing you to change between Square, Circle and Polygon drawing mode. Being able to use all of these as drawing tools will make your regular workflow much more efficient.
- anima® can now open multiple scenes at the same time! You will now see tabs on top of the editing view indicating what scenes are currently open. By clicking on a tab you can easily switch to the scene you’d like to work on. You can select multiple scenes when opening a project to indicate what scenes you’d like to open at the same time. Make your workflow much more efficient with these new possibilities!
- New tip system! Helpful tips are now provided on the bottom of the editing view when using most of the tools. This should help you find out quick shortcuts that will make your workflow much more efficient. You can disable these tips from the display preferences menu if you no longer need them.
- The display preferences toolbar option has now been moved to the top-left of the editing view along with a more representative icon. You should be able to spot this panel much more easily now.
- The “Shadows” and “Shadow Quality” setting have been both merged into one single setting. The quality setting has now been changed to a preset instead of a resolution.
- The new default play mode will be the “Preview” mode, which hides all visual helpers and lets you focus on the contents of your animation. You can switch back to the regular play mode by clicking on the small arrow on the play button.
- It is now possible to press the Space key to toggle between playing your animation or stopping it.
- Holding the shift key will now allow you to continue performing various drawing actions even after the first one has been performed. This also works when dragging nodes around the screen, allowing you to easily clone nodes.
- Libraries will now display how many items are being filtered when using the search function.
- Exporting a project pack will now display a percentage progress.
- Reduced memory usage in Editing mode. Models that are no longer being used will now be unloaded when selecting various models on the Actor Model & Motion editing mode.
- Several minor UI style improvements have been made across the board.
IMPROVED VIEWPORT
- Improved camera controls! Rotating the camera when a node is selected will no longer “snap” the camera to the selected node, and will now allow for a much smoother rotation instead. The camera speed is also now dependent on the distance to your scene, so you can easily move around large distances when needed. The “Zoom All” option will also now preserve the direction your camera was facing.
- Added a new camera preset designed to resemble Unreal® Engine’s controls.
- New shading system! anima has now switched to a Physically Based Renderer, giving you far higher quality visuals to preview more easily how your actors will look in your renders. The quality of materials has been significantly improved, and shadows will now act more realistically on both the actors and the background models, improving depth perception overall. The switch to a new renderer enables us to do some pretty exciting features in the future.
- Paths have been made more transparent to improve the visual style of the application and allow you to easily see overlapping paths.
- Video previews will now include the ambient occlusion effect along with all the other visual improvements.
- A new soft shadow is now displayed below the actors on both views when previewing actor models or clips.
- A new escalator step mesh with improved visuals has been included. This mesh will also be displayed on the Plugins and Exporters.
NEW BACKGROUND WORKFLOW
- New backgrounds panel! Backgrounds can now be shared in the same project between different scenes without having to re-import them. You can also find all your imported backgrounds in the new panel along with thumbnails and screenshots to easily visualize them. Simply drag and drop one of these backgrounds into your scene to use them! anima also comes with some new system-wide backgrounds for you to easily try out this new feature without having to import a custom model on your first attempt. (NOTE: The “Import background model” option from the context menu of the editing view is no longer available. You will find this option by clicking on the + button on the new backgrounds panel)
- Added the right-click option in the view-port for importing a background model.
- Many improvements to the backgrounds system! Since backgrounds are now a shared asset of the project, this means many performance improvements were made to take advantage of this. Moving or rotating your background model will no longer cause the simulator to recalculate all the collision data. The only parts of the simulation that will be recalculated is the surface detection when you rotate the background model. Since the collision data and models are now shared, this means the overall size of a project will be much smaller if you were prone to reusing one background across multiple scenes.
- Many improvements to the surface detection for background models. Small surfaces that are not usable will now be filtered and step detection should be significantly more accurate.
NEW MOTION CLIPS
- New motions! A great deal of the motion clips included in anima have now been replaced with new higher quality motion captures, giving you better results in your resulting animations.
- Actors will now react to harsh turns in more realistic ways. They’ll now change their walking lane so their trajectory ends in a smooth curve instead of strictly following along their current lane.
AREA TOOL ENHANCEMENTS
- Squares can now generate purely random distributions of actors when no grid or no points are placed on it.
- Raised the limit of area sizes for Squares, Traffic Lights and Avoid Areas and allowed typing bigger values if necessary.
ACTOR AND ANIMATION IMPORTER ENHANCEMENTS
- You can now install .y asset files by double clicking on them directly. This will work if you have anima already open. This functionality has also been extended to opening .aniproj and .anipack files directly into your current anima instance.
- The model importer now supports non-8 bits per channel textures by converting them to the correct format.
RENDER NODE ENHANCEMENTS
- Added an option to access the configuration panel and set a default Purchase Folder path. This will improve the network workflow for local render farms.
- Render nodes won’t need writing permissions on the network directory where the project is and still render out correctly, because the plugins will now use a system path for the texture cache if the directory of the project is protected against writing.
- Smaller exported project packs for external render farms because they will no longer include unused textures in the assets, bringing down the total size of these packs by a large margin.
INSTALLER ENHANCEMENTS
- The application has been updated to use the latest version of the Visual C++ Redistributable 2017 Package. That package has been included in the installer.
- A new “anima® Safe Mode” shortcut will be created when installing, allowing you to configure the application before it starts. This will allow to change the anima® renderer from OpenGL to Direct3D (or viceversa) in case there is any GPU driver issue after the first boot of anima®.
- Whenever a supported plugin application that has not been detected is checked manually, the installer will now ask the user to manually select the directory where that application is. This should help users who have installed their 3D applications in non-standard paths to be able to always use the installer as intended instead of performing the process manually.

anima® 2.0
Anima 2.0 is a completely new version of Anima, rewritten from scratch and better than ever.
REWRITTEN FROM THE GROUND UP
- Anima 2 is a completely new application, rewritten from scratch, and improved in every way.
ARTIST FRIENDLY
- With a completely new WYSIWYG editor, Anima 2 makes crowd simulation simple. It’s as easy as drawing a path, adding actors and hitting play.
RAPID SCENE POPULATION
- Whether a project requires one thousand characters or just one, Anima can spawn and simulate crowds of any size while adding subtle variations in textures and motions for incredibly realistic animations.
USE ANY ASSETS
- Users are not limited to the bundled content. Using Anima’s editing tools it’s easy to import and use 3rd party rigged characters and motion capture data.
MOTION AND POSE EDITOR
- Fine-tune characters and motion clips with the visual pose editor, providing the ability to adjust the rotation of every joint. Also edit and loop motion clips using easy-to-understand tools.
REALISTIC INTERACTION
- Anima creates natural looking crowd simulations using a sophisticated AI brain to anticipate collisions between actors and blend flawlessly between motion clips.
COMPLETE CONTROL
- Precise control is possible when it is needed. Each actor is fully editable, providing complete control to direct the perfect animation.
WALKWAY TOOLS
- New walkway tools provide sophisticated controls to direct walking, running and other locomotion animations. Advanced settings give users the power to control distribution, spacing, direction, clustering, and the ability to change the width of the path at any point.
RAMPS, STAIRS, ESCALATORS, AND MOVING WALKWAYS
- Use Anima to add actors that walk, run, navigate slopes, ride escalators, tackle moving walkways and climb stairs realistically. Whatever a scene’s topology, characters can explore every corner.
STANDING CHARACTERS
- Fill scenes with fixed standing and seated characters using an extensive range of animations, or import more from 3rd party sources. Characters can move from walkways to fixed areas to socialise.
PHOTOREAL
- Anima 2 uses the same high quality 3D people found in the Metropoly collections, so there’s no need to compromise on quality. Actors are driven by real mocap data and a sophisticated AI engine with automatic procedural motion to achieve super-realistic animations.
NO NEED FOR POST PRODUCTION
- Save time in post production! Anima’s 3D characters look great from every angle and interact with the lighting and shaders in a scene to create accurate shadows,reflections, motion blur, depth of field, and colour balance.
