Don't render final image – Image rendering is bypassed, allowing for other calculations, like texture baking or GI caching.

Secondary rays bias – A small positive offset applied to all secondary rays. This setting is useful when the scene contains overlapping faces, which can cause black splotches to appear in the rendering. For more information, see the the Secondary Rays Bias example below. 

Clamp max ray intensity – Uses the Max ray intensity value to suppress the contribution of very bright rays, which can typically cause excessive noise (fireflies) in the rendered image. The Max ray intensity value is applied to all secondary (GI/reflection/refraction) rays as opposed to the final image samples, allowing fireflies to be effectively suppressed without losing too much HDR information in the final image.

Max ray intensity – The maximum ray intensity when Clamp max ray intensity is enabled. 

GI texture filtering multiplier – Controls the filtering of all the textures in the scene when Global Illumination is calculated. Greater values make textures blurrier while smaller values make them sharper. When using V-Ray GPU renderer, this option is not available.

Up Vector – Specifies the up-vector for the scene. This setting can be useful when importing data from other applications (such as 3ds Max) where the up-vector is not Y as in Maya.

Cache geometry plugins between renders – When enabled, V-Ray keeps all loaded geometry in memory after the rendering is complete, allowing the next render to start faster in cases when the geometry is unchanged.

Clear geometry cache – Manually clears any geometry cache left between renders. Otherwise, the geometry cache will be automatically cleared on the next render if Cache geometry plugins between renders is enabled.

Cache bitmaps between renders – When enabled, V-Ray keeps all loaded textures in memory after the rendering is complete. This means the next render can start faster as textures don't need to be reloaded.

Clear bitmap cache – Manually clears any bitmap cache left between renders. Otherwise, the textures cache will be automatically cleared on the next render if Cache bitmaps between renders is enabled.

Use Maya shader for V-Ray proxies – For scenes created before V-Ray 3.1. Determines whether a proxy is going to be rendered with materials connected to the original mesh, or materials connected to the proxy instance.

Clear V-Ray proxies preview cache – Manually clears proxies preview cache. VRayProxy nodes allow caching of the geometry for faster preview; clearing the cache saves memory, and also makes it possible to reload the proxy if it has been changed.
