radiosity and rendering

[Bduggan04]

This is straight form the 3ds max 5 manual, and it holds true for six:

Object Animation
The radiosity solution is calculated for each frame if any object is animated in the scene (the default is to calculate the current frame only). You specify the parameters (goals/quality) you want to reach in the Advanced Lighting dialog. It is recommended to run a solution first and verify if it’s successful before proceeding to the whole animation. These parameters will then be reprocessed for each frame.

You go to the render dialog, Common Parameters rollout, and enable the option Compute Advanced Lighting When Required, and then render the scene. The radiosity is processed for the first frame and then rendered. 3ds max then moves to the next frame, processes radiosity, renders, and so on.

Hope this is sufficient.
