are these previews in 128x128?
well i love the smoothnes you can make at your sets/heads/art.
and i can record vids >=]
i use fraps to record and sony vegas 9.0 ( must be bought ) for my vids.
if you want to sell your sets you will need to rezise the textures after you made them.
cause when you upload 512x512 legs they are so crappy
