Trying to 3D Flip Y does not reset if you have the slider at 180 degrees and switch to no rotation. For example, I had a font icon that I was trying to flip horizontally, and oddly enough, the 3D Flip Y does that (more on that bug in a later post). However, switching rotation to off did not reset the Y flip parameters. I don't know if this is a known bug, or if it is a bug, but it confused me.
