Animation with Radiosity
By default, a
radiosity solution on page 5976 is calculated at the current frame.
If you are animating objects and you want to perform a radiosity solution at
every frame, select Compute Advanced Lighting When Required in the Render
Scene dialog > Render panel >
Common Parameters rollout on page 5929 >
Advanced Lighting group.
Once the renderer starts processing each frame of your animation, the radiosity
solution will be computed for each frame as required. This occurs, for example,
when an object moves, or a light intensity changes. If nothing changes in the
scene from one frame to the next, the radiosity engine will not recalculate
the solution.
NOTE Due to the random statistical sampling used by the radiosity engine, there
might be some flickering between frames. If this occurs, increase the value of Initial
Quality or the number of Refine Iterations to solve the problem.
