Decals

A decal is a material projection on the surface. In fact, decals perform changing material parameters of the surface on which these decals are projected. It allows you to add a lot of additional details at basically no performance cost. Decals are rendered in buffers (they change buffer textures) and works only with deferred objects. A decal is a perfect object for bullet holes, bloodstains, ashes, etc.

Decals support decal_base material only. The behavior of decals is similar to detail textures of the material.
