In this YouTube tutorial(http://m.youtube.com/watch?feature=plcp&v=LI4ZHVDuiKo) this guy his over vertex painting. My question is on the wall model. How does he get the 512 pixel image to tile correctly. Are your UVs for the color channel supposed to be overlapping?

UV's work in a relative kind of way. The wall may fill a square in UV space, but in the material applied to the UV may have different tiling so it doesn't look repetitive. Say the tiling is at 1x1 it would tile horizontally once, but if you set it to 1x2 it would tile twice. It depends how the UV's are laid out for the wall and how the texture is tiled within the material
It is then Linear Interpolated with another texture which makes it look even more varied. And obviously, you can make this setup as complicated as you like. -
They won't overlap, they will go beyond the 0-1 space to create the tile. Overlap can create the same result but it'll mean creating UV seams which is a bad thing in this case.

Thanks guys. I was a bit confused as I could see the tile on the texture but the wall was one piece.Comment
