interesting point: I copied and pasted a human figure from another drawing, and it works just fine.
also, on the one that works, in Wireframe rendering, the colors of the lines matcht he colors of the attributes(ie, shirt's purple, pants are black) but the ones that stay gray, their lines are all the same color.
Is there a setting I'm missing?
As far as I know, I created them the same way, witht he same attributes.
thanks
