Another advantage of the GPU sprites, besides being able to spawn large numbers of particles, is that it is possible for them to cheaply collide with the environment. This is handled by way of a Collision (Scene Depth) module, which allows a GPU particle system to collide with geometry based on Z-Depth.

The nice thing about the module is that you do not have to worry about any collision surfaces for meshes in the scene. Since the module uses the Z-Depth buffer from the GPU, you automatically collide with any visible geometry. The Collision (Scene Depth) module provides you control over resilience (bounciness) and friction.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
