Chapter 8 - Render to Texture (3ds Max 2010 Architectural Visualization)
One of the main techniques used to reduce rendering calculation time is to remove all light calculations from a scene. In real time 3D, it is done by pre-processing all lighting solutions prior to loading the 3D content. All these light calculations, complex or not, are put directly into the texture maps of the models. This process is called render to texture or texture baking.
