This is the first release of a simple, GPU-based 3D particle system for Castle Game Engine. You can find it in this github repository.
It also includes a simple particle editor as part of its demos:
- I originally planned on doing soft particle and screen-space physics by sampling the depth buffer. However it will mess up the current ScreenEffect system if I setup RenderToTexture manually. So I will wait for ScreenEffect rework first and see if I could work around the new system
- Currently its only useful for effects like dust, fire, smoke, fountain etc. Other effects that require trails like sparkle, or rotating in space like falling leaves are not supported yet.
