These are two scripts to clean up the scene. The first one, originally from corona renderer forum, is very effective for cleaning up garbage such as cache in 3dmax (the scene suddenly becomes larger, which is very useful).

It took me a long time, and later I found that this super cleaner often made mistakes when cleaning up lost maps, especially after importing too many models into your scene, it would be slow to respond and collapse directly.

Later, I went through a lot of trouble to find the second artifact, and it was completely easy to clean up the lost map.
