Problems with physics collisions

i have a scene where i have balls falling down and i have to avoid them hitting the floor with a paddle, so i use physics so that the balls bounce back and collide with the walls, etc. The problem is that i don’t want the balls colliding with each other, how do i do that?

Hello Diegocs,
You just need to use collision filters. Refer to the detailed document that I wrote on this, which should help you figure it out.
