Question by metroidsnes · Aug 29, 2014 at 07:26 PM · particle systemshurikenclipping

[Shuriken] How to avoid clipping?

Hi, I'm using particle system to emit cube shaped meshes. Problem is that the cube graphics is clipped on collision with the surface. How can I avoid that?

What do you want to happen? The cubes to bounce off?

I want the cubes to be fully visible (not clipped) when come to stop.

Particles use a simplified system for collision detection. Only the particle's origin is considered. As far as I know, there's no way to change this behavior. If this clipping issue is a deal-breaker, you'll need to spawn rigidbody cubes instead of using particles.

IIRC, I once used a particle mesh whose origin was offset to lie on the bottom face. Using this method, no clipping occurred, but this was done to achieve a very specific effect (game was very stylized, particle cubes represented "3D pixels")

You could disable depth testing on their material. The trouble is this could make them get render over the top of things you don't intend.
