Hey, I have another question which might be easily answered by somebody who is very familiar with the pixi sources. I'm in the progress of writing some custom classes to render a particle system. The particel rendering is all fine and working. I made some pretty good progress so far. I have a small customized PIXI.Container with a PIXI.ObjectRenderer and custom shader (it's like a sprite is rendered through the SpriteRenderer). As I said, this really works rock solid at the moment, I have learned a lot from the existing Particle/Sprite Renderer and I'm really impressed how many great examples
