Hi, I’ve noticed that many people are looking for solution for using particles in GUI in efficient way. So I’ve released new plugin: UI Particle System. With it you don’t need to deal with sorting layers or multiple canvases. It works like depth buffer but for GUI. Additionally it can clip particles in scroll views, etc. so you can make a lot of cool game effects or even card animations like in Hearthstone.
