## Detailed Description

Baking functionality.

The MPxBakeEngine class is a way for users to override the viewport representation of shaders. Users can provide their own baking engine to bake advanced shading properties into a texture. This texture is used by the viewport to represent the shading properties.

`#include <MPxBakeEngine.h>`
