General

This tab contains options that control the performance of the V-Ray for Softimage scene exporter (translator). The key feature controlled from here is "incremental export":

Options

Do not texturate objects with nodes more than - turn this option on to avoid exporting individual UV information for meshes with a large number of triangles. This may cause incorrect rendering but will speed up the export substantially in some cases. Typically only turned on for preview.

 

Max nodes - the number of geometry nodes over which the "do not texturate" option will take effect

 

Enable incremental export - controls whether incremental export is turned on or off for the scene, as explained above. It is very important that, if the scene has different sets of render options (per pass, or per viewport), all of them have the same setting for this check box. This will prevent confusion from the option being turned on for some renders, and off for others. There is only one, global incremental cache per scene regardless of the number of passes or viewports.

 

Clear export cache - press this button if, for some reason, the incremental cache or scene tree caches of V-Ray become de-synchronized from the Softimage scene (this behavior is normally related to minor bugs in the underlying platform). To have quicker access to this feature, you may find it useful to assign a keyboard shortcut to the ClearVRayGeometryCache custom command.

 

Additional .vrscene options

 

Export to a separate .vrscene files - when this option is enabled V-Ray will export separate .vrscene files for the different scene components like bitmaps, lights, geometry, materials, nodes, textures, RenderView (the settings of the standard Softimage camera) in addition to the main .vrscene file holding all the information

 

Write mesh data as binary - when this option is on the mesh data will be written in hexadecimal format in the .vrscene file. This makes the files smaller and faster for processing but it is harder for people to read them. When this option is off the mesh data will be written in normal decimal format as a text.

 

Write transform data as binary - when this option is on the transformation data will be written in hexadecimal format in the .vrscene file. This makes the files smaller and faster for processing but it is harder for people to read them. When this option is off the mesh data will be written in normal decimal format as a text.

 

Compress binary data - when this option is on binary data will be compressed to reduce storage size. Decompression happens automatically during rendering.
