Hi,

I want to spawn particle effects on bullet impacts. I set up some Physical Materials, added them also in the Project Settings and applied them to the Materials. And with this Blueprint only the default is triggered and never anything else.

So what is the problem and how do I solve it?  
Thank you!

Where did you set up the physics material? Inside Collisions → Physics Material Override?
