The Shader resource type is the primary shader type in Burnout Paradise. It is effectively a wrapper for a heavily modified Shader Technique resource. It is used in conjunction with the Shader Program Buffer type, which holds precompiled shaders.

In the original PC game, no program buffers are imported. Instead, the game compiles the shaders at runtime using included source code and caches them for later use.
