Development Information on versions of the Shader Technique resource type used during development.

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

This type is only used on PlayStation 3 and Xbox 360. In the original PC game and Remastered, it is replaced by the Shader resource type.
