I was looking forward to sculpt tiling textures in 3d coat, ever since I caught a glimpse on the "Tile box 3x3" option in the Surface Sculpt Welcome screen. I was under the impression that it will just work as it says. Unfortunately it is not. You can not paint across instances, which is a huge oversight imo. In addition, the template setup has the tiles overlapping, causing seams between them when you stencil project something. It is really just an instance tiling rather than the true Tiles
