Is driving me absolutely crazy. It renders out differently than it looks in the panel view, you click off of one thing and the hair dissapears, you click on something else the hair looks entirely differently, and at one point it shows the modifications I made with brush and scissors and the next moment it does not. Either this is extremely buggy or I'm missing something.
EDIT: I think I know why it wasn't working. I was pushing the hair strands around in points mode, opposed to tips... and pushing things around with the brush and cutting seems to ONLY work for me when I'm using Tips opposed to points mode. I haven't tried messing with roots yet.
