PhysX Painter is made to quickly populate your scenes with your assets in a very natural way.
Using a brush, it automatically places them with Rigid bodies simulation.
Whether you work in architecture, game cinematics, commercials…etc you very often need to add details to your scenes with some assets. Placing them by hand is tedious and takes time to get a natural look.
You also probably tried to do that with MassFX simulations or particles, but it takes time to get the result you want.
