I’ve made rain and snow particles for my project. They look great, but having a top-down 3D game it gets annoying when they’re constantly in the camera’s face. I figured I’d set up a sphere collision volume parented to the camera in my player blueprint that kills particles on overlap, but it doesn’t…

Found it! Under the collision module on the emitter, choose your custom collision trace channel under the “CPU Collision Trace Channel” dropdown there (and then obviously tell your volume to block the same channel). Works like a dream!

Hey there @Maladrum ! I’m not so much a Niagara guy so I’ve got some documentation on the collisions for the system, but it seems like it could be heavy if you have tons of particles. Feel free to take a look and let me know if this helps Collisions in Niagara for Unreal Engine | Unreal Engine 5.0 Do…

However, this doesn’t solve the issue; this is just a solution to kill particles on ANY collision, not specifically when they collide with the specified volume. I actually have this already set up for other purposes. But it has gotten me thinking…

also you can do material fade by camera distance for particle material
