Vray Blend Material can be used to layer several Vray materials in an efficient manner. It can be used to create complex materials like car paints, human skin (when used with SSS as a base material) etc. Vray Blend Material 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.

Basic Properties

Name – here you can enter a name for the object.

Layer – If an element was assigned to a layer its layer color will be displayed here. This field reflects the layer color in the Layer Palette. You can drag & drop layers from the Layer Browser or similar layer fields onto this field. You can also assign layers or remove elements from current layers using the menus located behind the small triangle.

Preview Quality – quality of material preview in preview window.

Map Preview Size – Here you’ll find entries from 64×64 (16 KB) to 4096×4096 (64 MB). The value controls the internal resolution of the map — the higher you set this value, the more detailed the map will be in the Viewport. The value has no effect on the rendered result.Proceed with caution when increasing the Map Preview Size. Higher settings require more RAM and increase the file size of the CINEMA 4D scene. OpenGL is also affected because the map previews must be loaded into the graphics card’s memory.

Overridable – when you use Override material options in Global options, you can specify some materials that will no be override, like glasses, curtains etc..it useful for preview vizualization of interiors.

Round Edges – edges of object with this material will be rounded.

Parameters

Use Material – enables or disables use of Coat Material.

Coat Material – these specify materials to use as coatings.

Base Material – the base material over which other materials are layered. If this is not specified, the base material will be assumed to be a perfectly transparent material.

Assignment

In this box, you’ll find a list of all objects in the scene that use the selected material. Using the context menu, you can carry out commands on these objects that relate to the selected material. To open the context menu, right-click (Windows) or Command-click (Mac OS) on an object’s name in the list.
