Ouch. That means every side of a texture has to be tilable with every side of every other texture, regardless of relative orientation. That is such a severely limiting problem it makes the feature unusable for the majority of instances, because only in a few very rare circumstances would a pattern look okay this way. Can you suggest something else? Maybe I can create 4 tile sets for the terrain, for N, W, E and S? Otherwise just having a 9-tile set for terrain would fix all potential issues. Yeah, it seems that a tool in my current project is interfering with UniRPG. A new project resolved the issue, so that seems okay... Thanks.
