Tutorial / Random object visibility in 3dsmax with MaterialByElement & Opacity

This simple 3dsmax technique is quite useful when you have to trigger the visibility of numerous objects. Instead of deleting “randomly” some elements, you apply randomly materials that are visible… or not. This is a very simple flexible method, and it works normally with any rendering engine inside 3dsmax. It doesn’t involve any script (although I think it can be improved with scripts)
We’ll take this 3D array of cubes for example, collapsed in the same object. LINK
