I've imported the "black face" model to experiment with for creating an alien. I've pulled the head into a different shape and am getting a bit of a feel for the tools, but one thing I'm puzzled with is painting/changing the color.
I found the paint brush under UV & Paint and I've selected a new color, but when I go to paint I get a red circle with a big blue dot on one side, and a red circle on the other (symmetry). But despite clicking here, there, and everywhere, nothing seems to happen. I'm obviously missing something (lol).
