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.
Types of Decals
There are 3 types of decals:
- Orthographic Decal is a decal projected onto a surface by means of orthographic projection.
- Projected Decal is a decal projected onto a surface by means of the perspective projection.
- Mesh Decal is a decal based on the arbitrary .mesh file and projected onto a surface by means of the orthographic projection.
