I’m tying to use a particle effect for dust and debris generated by projectile hits, and I want the dust to be blocked by walls and other solid objects so it doesn’t pass right through; but when I enable particle collision, the dust particles push walls that they hit, sometimes to the point of knocking the wall down. How do I prevent force being applied by the particles while still allowing them to be blocked by objects?
Make your walls static. I believe that marks them as immovable objects to the Physics engine.
