I got the UV thing to work . But still no paint. I have a sphere uved, then even applied domains made sure I selected the paint texture etc, but can't paint. So I am missing something about this "reveal' approach. Still looking thru docs. Looking at the bug reports some are just plain silly. Gotta be fun to go thru that. At least they listed it as trivial. Were they trying to be funny or what? Maybe just helpful. So anyone who has "mastered" the paint thing, I would love some info.

Reported by a user from bug reporter:

Summary 0010463: 'Ambient' is spelt wrong Description 'Ambiant' is used throughout Hexagon 2, but is incorrect spelling.

No need to think outside the box....
