Extended motion blur support on V-Ray GPU

Leverage GPU power to add motion blur to splashes and bubble mode in the Particle Shader.



Faster rendering and simulations

Take advantage of various speed gains on simulation, rendering and previews.

Property Lister window

Quickly access and change the Phoenix properties of each object in your scene—all in one place.

Autodesk 3ds Max 2022 support

Phoenix is now compatible with the latest Autodesk releases.



With Phoenix FD 4.40 we added support for 3ds Max 2022 (note that the GPU preview and velocity streamline preview are disabled temporarily due to changes in the 3ds Max viewports).

We implemented mutual collisions between Active Bodies so now you can create complex rigid body dynamics with Phoenix. In order to aid scenes with many interacting objects, we added a new Property Lister window, allowing you quick access to the per-node properties of the scene nodes.

Simulations of large scale stormy oceans or tunnel waves are now possible with the new Massive Wave Force.

A new colored absorption option allows for more interesting volume rendering effects, and can also be mapped via a texture. We added support for motion blur of Bubbles and Splashes in V-Ray GPU (requires a latest V-Ray 5).

The Phoenix standalone previewer can now be fully controlled via the command line, allowing you to change options and save image sequences of cache files in all different preview modes.

In this version of Phoenix, we multithreaded all remaining parts of the simulation, and also sped up the simulation, previews and rendering significantly.

We improved our toolbar presets, added more options to the cache converter tool, and as always, fixed many issues.
