TIP Before launching a lengthy animation with radiosity, you should process a
radiosity solution manually for a single frame to make sure the results are
acceptable.
TIP If you animate only your camera (as in an architectural walkthrough) then
you can calculate a radiosity solution for only the first frame of the animation, and
reuse it in all subsequently rendered frames by turning off Compute Advanced
Lighting When Required on the Common Parameters rollout of the Render Scene
dialog.
Avoid using the
Automatic Exposure Control on page 6534 for animations.
This exposure control can change from frame to frame, creating a flickering
effect.
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 on the Advanced Lighting
panel. 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.
Camera Animation
If objects remain static in the scene and only the camera moves, you can solve
radiosity at frame 0, and when you render the animation, turn off Compute
Advanced Lighting When Required.
Radiosity Controls

renderer. > Advanced Lighting panel > Choose Radiosity.
