Things to try to speed up exporting heavy and animated scenes in V-Ray

[GidPDX]

Vladimir was nice enough to compile a list for us on Skype of some things to try to reduce export time and sometimes size of exported files. I thought I'd post it here so it's not lost to the sands of skype/slack time:

• 1. Make sure to triple all polygons with >5 vertices.
• 2. Turn any meshes you can into "static meshes" if possible.
• 3. Delete any unused part/selection tags on your meshes.
• 4. If possible, enable V-Ray subdivision on your meshes, especially deforming ones. This way V-Ray for Modo has to only export the subdivision cage, not the fully sub-divided mesh. Subdivision in V-Ray will probably be (much) faster than exporting the Modo one. This will also reduce the size of the .vrscene file, so it will speed up upload for DR and Chaos Cloud
• 5. Light cache on or off doesn't matter for the export of the scene.
• 6. If you have to use Modo subdivision, make sure that the "Subdivision" and "Render" level are the same. At least in older Modo versions, there was a performance bug which would make the export very slow if the two subdivision levels don't match. Not sure, if it was fixed since then.
• 7. Use V-Ray Fur instead of Modo Fur, if possible and make sure the "Render Cache" option is disabled.These are the most important. Might also reduce ,vrscene file size, as the V-Ray Fur is generated at render time.

Very nice!
