Matte Layer

General

Material Matte Layer is a tool to make much more easy compositing session, think about it like a object matte in c4d compositing tag, but at material level, for example if you have a scene with some back object an one character,with black hole mode you can render a static backgrounds character with in black Hole mode and then you can make another render with character and back in black hole, with this situation if you need to change some thing in character, you can rerender only it and not the back, you can use it to isolate object and fake inclusive or exclusive lighting in various part of the sceneand it can be used to make object and material ID with AA and Physical Camera. 

Parameters

Matte Mode - This option allow choose matte mode:

 

Matte Opacity - XXXXXXXXXXXXX.

 

Invert - This option simply inverts the  Matte Opacity.

 

Alpha Transparency -  XXXXXXXXXX.

 

Invert - This option simply inverts the Alpha Transparency, so transparent and solid areas are reversed. This works for both clipped images and images with built-in alpha channels.

 

Map Preview Size- Here you’ll find entries from 64x64 (16 KB) to 4096x4096 (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 filesize of the CINEMA 4D scene. OpenGL is also affected because the map previews must be loaded into the graphics card’s memory.
