I can't wait to see where this software will go. I'll try and play with some nodes, maybe i'll find something that works. I think BlackInk has great potential to become a 3d modelers tool. Especialy now with the tileable function. What would make it perfect though is being able to keep the tileing while painting, so the changes you make at any particular edge, would be reflected on the opposite one, making the texture seamless on the fly. On the side note, this is also great for making custom aplhas for sculpting.
