• FilterBox - All samples within a box with sides 2*size are taken with equal weight.
• FilterArea - All samples within a circle with radius size are taken with equal weight.
• FilterTriangle - Sample weight falls off as a triangular function of off-center distance.
• FilterGaussian - The classical blur filter.
• FilterSinc - Less blurry low-pass filter. See Wikipedia.
• FilterLanczos (currently default in V-Ray for 3dsMax and Maya) - See Wikipedia.
• FilterCatmullRom - A cubic edge-enhancing filter.
• FilterCookVariable
• FilterMitNet - Mitchell-Netravali filter. It has cubic filter with subjectively optimized compromise of blurring and detail in the additional blur and ringing parameters which correspond to B and C from the original paper.

See 3dsMax docs or Maya docs for more info on filters.

Note: Do not create a SettingsImageFilter. It is deprecated. Use the plugins described above.

You can define environment background, lighting (GI), reflection, refraction colors or textures through the SettingsEnvironment plugin. Usually all slots have the same value. You can also add scene-wide volumetric effects through the environment_volume list.

...

A special case is the Sun-Sky system. V-Ray has a special procedural texture, TexSky, for these environment slots (you'd usually want to set it to all slots) that is coupled with SunLight. The color of the environment depends on the position of the Sun.

• Change the type parameter of SettingsCamera to 10.
• Set a resolution with aspect ratio 6:1 or 12:1 if you are doing stereo. So for a stereo cubic panorama with 1000x1000 pixel cube sides you will render at 12000x1000.

6.9. RT Engine

6.10. Miscellaneous

The SettingsRaycaster plugin has one parameter of interest: embreeUse. You'd want to set this to 1 (default is 0), because it increases raytracing performance.
