Irrcaches that only affect the group/component they're in

And let the rest of the scene simply use the skybox...

This could be useful if you have a couple of mirrors, each with its own irrcache, but you don't want the floor reflections to become split between these irrcaches.

Yep, Excellent suggestion.

If we get that ability I think it would also be great to be able to set the size of the reflection cubemap. For example set it very low to simulate blurry reflection on metal and such.

I'm not sure that setting a reflection map to a lower size might help simulate metallic reflections. Instead, the reflection map must be blurred for that. With a small reflection map all you get is ugly aliasing in reflections.

+1 for this

and +1 for this too. It would be handy to set the resolution of the irrCache to something high for a flat, smooth mirror. For surfaces that are very bumpy or diffuse a high resolution irrCache isn't really required as the bump map does a good job of 'blurring' the irrCache. Also some blurring effects would be cool, like a radial blur for some diffuse metal that can't be easily replicated by a bump map, and also a directional blur for some finely curved surfaces?
