General

VRayBlendMtl can be used to layer several V-Ray compatible materials in an efficient manner. It can be used to create complex materials like car paints, human skin (when used with VRayFastSSS2 as a base material) etc.

 

You can use the VRayMtlSelect render element to split the different sub-materials of VRayBlendMtl into different render elements.

 

VRayBlendMtl takes a base material and applies other materials (coatings) on top of it. This works like a stack, where each coat material blends between its own shading and that of the materials below it in the stack.

Parameters

General

Base material - the base material over which other materials are layered. If this is not specified, the specified color will be taken into consideration instead.

 

Coat materials - these specify materials to use as coatings.

 

In use - this check box allows you to add or remove coat materials

 

Blend amount - this color specifies how much of the final result is contributed by the corresponding coating material, and the rest of the materials below it. If the Blend amount is white, the final result is comprised of the coat material only, and other materials below it are blocked. If the Blend amount is black, a coat material has no effect on the final result. This parameter can also be controlled by a texture map.

 

Additive (shellac) mode - checking this option makes VRayBlendMtl to behave like a multi-layered Shellac material. Note that this would often result in a physically incorrect material (e.g. a material that reflects more light than falls on it). It is not recommended to use this option unless you know what you are doing.
