V-Ray Scene

VRayScene allows for assets to be shared between all platforms that run V-Ray. It loads a previously saved .vrscene file into V-Ray for Cinema 4D and supports rendering geometry and materials. In addition, it allows you to load scene overrides from a .vrscene file.

To export a .vrscene file from Cinema 4D, go to File > Export... and select the V-Ray Scene option.

Drag-n-drop

To import a vrscene file, you can use the drag-n-drop functionality.

The VRaySceneImport window prompts you to choose how to import the file in Cinema 4D. See below for descriptions on all options.

File > Open Project

Go to File > Open Project and select a .vrscene file. The VRaySceneImport window prompts you to choose how to import the V-Ray Scene into Cinema 4D.

You can also merge a V-Ray Scene into your current scene by loading it from the Merge Project option.

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 settings as presets.

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.
Auto – It aligns the vertical axis of the vrscene with the vertical axis in the scene in cases where the vrscene was not exported from 3ds Max. Use the Auto mode when loading a USD file.
Z-Up to Y-Up – Switches the Z and Y axes.
Y-Up to Z-Up – Switches the Y and Z axes.

Enable Animation Override – Enables the following parameters found in the Animation Overrides rollout.

Speed – Determines the pace at which the animation plays. The default of 1 plays at the speed for which the animation was created.

Playback Type – Specifies how to read the animation in the .vrscene. 

Loop – Plays the entire animation, then restarts on the initial frame. 
Once – Plays the animation once, then displays the last frame of the animation for all further frames. 
Ping-pong – When the end of the animation is reached, the animation is reversed. 
Still – Displays only one frame.

Offset – Shifts the start frame.

Start – Sets the frame for the first frame of the animation.

Length – Sets the length of the animation. If this value is less than the total number of frames, the animation is clipped. If it is greater than the number of frames, the Playback Type option determines how the extra frames are interpreted.

Preview – Specifies one of the following modes for previewing the selected .vrscene in the viewport:

Preview Geometry – Displays a preview of the .vrscene using the value set in the Face Count parameter.
Bounding Box – Displays a preview of the .vrscene using bounding boxes.
Points – Displays the .vrscene using points.
Disabled – Hides the .vrscene.

Face Count – Determines the number of faces that are used for preview of the .vrscene file.

Through V-Ray menu

You can import a .vrscene file using the V-Ray menu. Select Geometry > V-Ray Scene.

From Attributes, go to the General tab of the V-Ray Scene. From File Path, select the .vrscene file. It loads in the 0,0,0 coordinates in Cinema 4D.

File Path – Allows you to browse for and specify the .vrscene file.

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.
Auto – It aligns the vertical axis of the vrscene with the vertical axis in the scene in cases where the vrscene was not exported from 3ds Max. Use the Auto mode when loading a USD file.
Z-Up to Y-Up – Switches the Z and Y axes.
Y-Up to Z-Up – Switches the Y and Z axes.

Include Geometry – When enabled, renders any geometry in the .vrscene file.

Include Lights – When enabled, renders any lights in the .vrscene file.

Material Override – Allows material override of all V-Ray scene materials with one selected in this field.

Enable Animation Override – Enables Animation overrides.

Speed – Speed multiplier for the animation. A value of 1 plays the animation at normal speed.

Playback Type – Specifies how to read the animation in the .vrscene.

Loop – Plays the entire animation, then restarts on the initial frame.
Play once – Plays the animation once, then displays the last frame of the animation for all further frames.
Ping-pong – When the end of the animation is reached, the animation is reversed.
Still – Displays only one frame.

Offset – Shifts the start frame.

Start – Sets the frame for the first frame of the animation.

Length – Sets the length of the animation. If this value is less than the total number of frames, the animation is clipped. If it is greater than the number of frames, the Type option determines how the extra frames are interpreted.
