See the Color Mapping section for more details.

Also use V-Ray's own Color mapping mechanism. Of the standard 3ds Max exposure control plugins, only Logarithmic Exposure control is fully supported. Exposure plugins that require presampling of the image (Automatic Exposure, Linear Exposure) or separate render elements (Pseudo Color Exposure) do not work properly with V-Ray. V-Ray supports exposure control only partially. See the Render Elements section for more information. V-Ray does not support the standard 3ds Max render elements, but instead supplies its own, both for normal rendering and for texture baking. Using it produces an entirely black image. Use the translucency options in the VRayMtl material instead. This shader is not supported by V-Ray using it is not recommended. This shadow type does not work with V-Ray using it is not recommended as it can lead to artifacts in the image. Instead, use the Dome mode of VRayLight or the GI Environment override option in V-Ray's Environment Settings rollout. The standard 3ds Max skylight is not supported by V-Ray, and V-Ray prints a warning about this if you attempt to render it. Instead, extended matte/shadow capabilities for V-Ray are available in the VRayMtlWrapper material or in the V-Ray Object settings. The standard Matte/shadow material also does not pick up GI shadows. Specifically, the Opaque Alpha parameter is not supported.

V-Ray only partially supports this material. Some of its functionalities are available in the VRayMtlWrapper material. This material is not fully supported by V-Ray using it with V-Ray is not recommended as it can lead to artifacts in the image. V-Ray does not provide an equivalent functionality.

This map is not supported by V-Ray using it with V-Ray is not recommended. This map is not fully supported by V-Ray using it with V-Ray is not recommended, as it can lead to artifacts in the image.
