File name – The source .vrmesh file. Animated proxies can be stored either in one single file, or as a sequence of files with one file per frame. In the latter case, you can use the string <frame0n> in the file name to have it replaced with the current frame number at render time, where n is an integer number specifying the number of digits. For example, if you enter my_proxy_<frame04>.vrmesh as the file name, this will be expanded to my_proxy_0000.vrmeshfor frame 0, my_proxy_0001.vrmesh for frame 1, and so on. If you use a sequence of files, the Playback type option is ignored, as V-Ray doesn't know how many frames are in the animation. The Playback speed parameter may also work unreliably with sequences of files.

note
The old formatting specifier %0nd is no longer supported since version 3.0rc (night build revision 24745), because we had to mark the filename attribute with the flag usedAsFilename and Maya doesn't allow the user to enter the '%' character as part of the file name for such attributes. Old scenes will be automatically upgraded to the new formatting. If you use the 'fileName' attribute in scripts it is better to use the newer 'fileName2'.
Placeholder (don't read proxy info) – The proxy is displayed as a simple placeholder box with fixed size.
Geometry to Load – Select the viewport preview mode from the drop down menu. This does not affect the final render. This parameter is Keyable and can be used as a driven key as Geom Type in the Channel Box.
Bounding box – The mesh is represented as a box scaled to fit the object in viewport. Preview – The mesh is represented as a low poly proxy preview as defined in the .vrmesh file. Maya Mesh – The original mesh is previewed in the viewport. Note that any edits made to this mesh do not appear in the render. GPU Mesh – The original mesh is loaded into the viewport using the GPU, which gives faster viewport performance and less memory consumption. Note that any edits made to this mesh do not appear in the render.
Cache geometry – When enabled the preview geometry for each frame of the animation is stored in the memory once it has has been previewed. This allows to speed up the playback of animations.
Viewport proxy file – Allows selection of an .abc or .vrmesh file to be used as a preview in the viewports.
Flip axis – When enabled, this option switches the axis being used by Switches the proxyas the 's vertical axis between Y and Z. It allows the user to align the aligning vertical axis of the proxy with the vertical axis in the scene in cases where the proxy was not exported from Maya or when loading Alembic files.
Particle render mode – Controls how the particles in the proxy are rendered in the viewports. The available options are Point and Sphere.
Tessellate hair – When enabled, tessellates hair strands for files containing hair.
Edge length (in px) – Specifies hair edge length in pixels for smoothing hair strands.
