Splat

A splat map is a texture which controls blending of multiple textures (or other values) across a model.

Splat maps are commonly used for terrains in games.

Each color channel of the splat map is a mask for a different texture. Usually four textures are blended, using the red, green, blue, and alpha channels of a splat map.
