Start/Reset Behavior

Display Reset Warning
When on, a warning message is displayed whenever you reset the radiosity solution in your scene.
Update Data When Required on Start
When on, the radiosity engine must be reset and then recalculated if the solution is invalidated. In this case, the Start button changes to read Update & Start. When this is pressed, the radiosity solution is reset and the calculation starts over again.

When this toggle is off, the radiosity solution does not need to be reset if it is invalidated. You can continue processing your scene with the invalid solution.

Note: The radiosity solution is invalidated any time an object or light is added, removed, moved, or altered in any way.

File Save group

Save Scene Information in MAX file (Decreases Load Time)
The light levels from the radiosity solution are always saved with the file, however when this is on, some additional radiosity information is saved with your scene.
