I love your shockwaves! I noticed you’re using mesh renderers. Did you use default engine meshes or make them yourself? I’ve been pretty basic with my FX since I’m typically making blueprints or other things. I get how to render a mesh to have the emitter take on it’s shape, but not so much on how to get alpha properties & other things going on to get cool patterns & stuff. The closest I’ve gotten to that is using Sub UVs for sprite flipbooks 
If you have a chance to check out my submission, I’d love your thoughts!
