VRayScene V-Ray Scene allows for assets to be shared between imported from all platforms that run V-Ray, as well as any CAD application with Enscape installed. It loads a previously saved .vrscene file into V-Ray for Cinema 4D and supports rendering geometry, lights, cameras, volumetrics, and materials. In addition, it allows you to load scene overrides from a .vrscene file. a .vrscene file. There are two ways to import a V-Ray Scene file - as a proxy or by importing all its assets as native components. Each Import Type has different benefits and can be used in different scenarios. For more information on Import Types, see the Import Types section.

Keep in mind that scenes imported using Currently, V-Ray Scene does not import are still foreign, and not all imports can be perfect - things could look different in their original environment and inside V-Ray Sky in for Cinema 4D.

as Native Objects (WIP) only if you import through the VRaySceneImport window. See the Different ways to import for more.

UI Text Box
typenote

This option is a work in progress - not all elements can be fully imported. Expect improved support in the future.

This Import Type imports the scene elements separately. This allows each element to be edited individually after import. This is ideal if you are finishing a scene that was started on a different machine or was created on a different V-Ray-supported platform. You can edit individual lights, geometry, materials, and more to complete the scene without needing to re-create everything from scratch. 

UI Text Box
typeinfo

Large scenes will take some time to load, as V-Ray Scene is reading all the individual elements and importing them separately.

If you are importing a V-Ray scene with Gamma corrections as Native Objects (WIP) from V-Ray for 3ds Max, please see this section for an import guide

V-Ray Scene Reference

The V-Ray Scene Reference Import Type imports the V-Ray Scene file as a proxy - its components cannot be individually edited, but the proxy can be edited as a whole. This Import Type is more compact and saves processing power. If no further edits need to be made to the scene, we recommend using this method for transferring V-Ray scenes.

You can convert a Scene Reference into a Native Objects (WIP) after importing.

The VRaySceneImport window prompts you to select some import options for the .vrscene file. The Presets tab is a Cinema 4D tab that allows you to save and re-use reuse settings as presets.

Import Type – Determines how the file is read when imported. See the Import Types section for more information.

Native Objects (WIP)* – The elements in the file are read and imported individually as separate native objects as if the scene was created locally. This allows for greater editability of the imported V-Ray scene. Keep in mind that not all assets will be imported properly due to their nature - elements that are not supported by V-Ray for Cinema 4D and elements that are not supported by V-Ray Scene, currently cannot be imported natively.
V-Ray Scene Reference – The file is imported as a V-Ray Scene geometry. Edits to the scene are limited to the V-Ray Scene parameters.

GENERAL

Flip Axis Mode – Controls which axis is used as a vertical - the Y or Z axes for the loaded vrscene. You can choose between:

As Is – No changes in the axes are applied.

Importing Native Objects (WIP) from V-Ray for 3ds Max with Gamma Corrections

...

...

Section
Column
width55%50%
UI Text Box
typenote

The TexMaxGamma node is imported from older V-Ray for 3ds Max scenes only when the Optimize Shaders option is enabled during import in the VRaySceneImport window.

If you are importing a .vrscene file as a Native Object from an older V-Ray for 3ds Max scene, the materials in that file will import into V-Ray for Cinema 4D only as classic materials with a VRayMaxGamma shader attached. This texture helps properly transfer the color settings. However, the VRayMaxGamma node can prevent the imported materials from being converted to V-Ray Node materials through the Convert Materials tool.

The exception is if the materials are exported with a Gamma of 1. In that case, they are imported into V-Ray for Cinema 4D seamlessly without the creation of a VRayMaxGamma texture.

If that is not the case and a different Gamma value is assigned to the materials, you need to adjust the settings of the VRayMaxGamma textures of each material. Keep in mind that these alterations might change the look of your imported shaders. You can either set the Color Space of the VRayMaxGamma to Linear and set the Multiplier value to 1 or set the Color Space to Inverse Gamma and set both the Multiplier and Gamma values to 1. These settings allow V-Ray to skip the VRayMaxGamma texture when converting, allowing the rest of the material to be converted into a Node material.

Scene Export

Separate files – When enabled, V-Ray exports separate files for different components of the scene. This also allows you to disable export for certain types of objects: Lights, Nodes, Geometry, Materials, Textures, and Bitmaps.

Each frame in separate file – When enabled, V-Ray makes a separate file for each rendered frame.

Strip paths – When enabled, the paths for assets (bitmap textures, proxies, GI caches loaded from file, etc.) are removed from the exported file and only the file names of the assets remain.

Write mesh data in hex format – When enabled (the default), the mesh data is written in hexadecimal format in the .vrscene file. This makes the files smaller and faster for processing, but less readable to a user. When disabled, the mesh data is written in normal decimal format.

Write transform data in hex format – When enabled (the default), transform data is written in hexadecimal format in the .vrscene file. This makes the files smaller and faster for processing, but less readable to a user. When disabled, the data is written in normal decimal format.

Compressed – When enabled, basic compression is applied to the .vrscene file. This option can only be used together with Write mesh data in hex format.

Skip exporting plugins

When exporting an animation, these options select which plugin to be included.

Skip Exporting Objects and Lights:

Export All – Exports only render settings and objects, and lights.
