I know that in your readme you say this is the first obj you have made. I could not have done it, which is why I downloaded yours, so thankyou, I think. I say that because I don't know if you have realised that when you swing the pentacle on the y axis the reverse shows the sign of the devil. In other words when you textured this you reversed your tex file up and down, not side to side. I only found out because I wanted the pentacle on its own, without the wooden background, so I made a trans map from your jpg and got a ten point star. Most people would not worry, but as a pagan I was a bit upset, and also now need to go back to the drawing board to find a pentacle for the image I have in mind.

The greatest part of wisdom is learning to develop  the ineffable genius of extracting the "neither here nor there" out of any situation...."
