I'm trying to add a little flashiness to my UI with some particle systems, and I'm running into a problem. I've got a particle system set up that I instantiate as a child of some UI widget, it's in the same layer as the UI and drawn using the same camera, everything looks great. Switching from an iPad2 to an iPad3, however, gives me particle effects that are a quarter of the size. On the retina display, the root of my UI hierarchy is being scaled up to twice the height and width to fill the extra pixels, but that scale doesn't affect the particle systems. Has anybody had any luck dealing with this issue? The best solution I can think of is to create separate versions of the effects to use on retina displays.
