Looks great and runs smooth I hope you make more particles in the future! Only thing I notice is theres is a snow texture that is like a cluster that kind of stands out once I notice in the first couple options that are heavier snow that isnt a big deal it just doesnt blend in as well as the rest.
Yeap I agree. I used the sheets to alleviate the cost on particles systems and give it a bit more density, but it works way better on still shots than in realtime with the dense ones. I'll try to see if I can improve that.
