Hello, I have a vehicle that is chasing a Niagara sprite particle effect (dust from another vehicle). I’m trying to keep the dust out of the inside of the vehicle, but my collision is failing somewhere:

The dust is still passing through the vehicle.

I’ve set up collisions on the vehicle:

I’ve also enabled collision modules on the Niagara particle effects:

I am missing the “collision Query” module that is often referenced in some of the help links or tutorials I’ve come across.

Maybe a better way would be to limit the opacity of the particle effect if it’s inside the shape of the vehicle somehow?

Or would it be better to work in the level blueprint to limit the visibility somehow of the particle effect once it enters a certain area?

Humbly hoping an expert has a moment to even point me down a specific path to pursue a solution?
