This is a free effect request thread.
Please, first check existing free effects:
Fire
Smoke
Snow
Rain
If you need a different effect of similar type, please make the request here. Just tell me what kind of effect you would like.
Notice: This is a time/resource limited effort from my side, I like to contribute and help but I don't have the ability and time to make every type of effect. Only effect requests that I can make in a reasonable amount of time will actually be accepted and made, but I will consider and think about every request I see.
Thanks for your understanding and suggestions.

Edit: I will release some effects here until I can group them properly into a new thread in the future. For all effects I release in this thread: License
