To be honest, I have never done hair purely in the top down view - so not an issue for me!
yes I found that in C6pro when I first got it and did hair back in 2009 and never tried it again!! I always use directors camera and a small brush size with symmetry toggling ctl or is it shift?? to clear bits.
WARNING do not click what will be seen if you do cannot be unseen.
The video for the track that I did the animation for has just been released, so you get to see more of it this time!

The animation kicks in around 4:00 (but I recommend watching it all!)
I hope you like it. It is looking to be an incredible album, I recommend buying it!
