Well, on my other PC, Blitz has no problems with them whatsoever, regardless of shape or size. Even the rectangle ones, it just scales them onto the shape. It doesn't matter if it's cubes or spheres or irregular objects - never had any problems at all.
Now all of a sudden on this PC, it can ONLY handle squares with a height/width to a power of 2 :/
