Ive dont that render. Its going in my pack. Not gonan publicaly realeae it..And it is actually really easy..Jsut time consuming lolz Mine was 1600x1200 though. Jesse
But then again, Jesse also has the googlebrowser... any way that render looks extremely time consuming, but good luck!
for that, i'd render with a brush. it'll be much less confusing but possible more time consuming. yes i said, render with a brush
Layer mask and black also work if you're gonna render with a brush. Good luck with the cut, by the way.
