The MultiMatte Materials Render Element creates red, green, and blue selection masks based on material's ID number. Please note that this channel does not take into consideration Material's ID color. With this render element, only three colors are possible: red, green, and blue. It analyzes the scene at render time and automatically creates the necessary number of channels based on the number of unique specified IDs. Each channel holds up to 3 unique IDs. Each channel's name indicates the IDs it represents. With MultiMatte, a single R, G, or B channel can be used directly as a matte, eliminating the step of selecting the color in the compositing software. This ease of use makes MultiMatte a popular choice for compositors. The MultiMatte Materials Render Element includes an antialiasing option. Besides this render element, V-Ray also supports MultiMatte Objects channel, which uses Object ID numbers. |
