I'm not sure if that absolutely has to be the case though...

The Ptex stuff for example basically has the equivalent of seams at every polygon edge, but apparently it also incorporates some mechanisms to make the transitions work better.

So I'd think it would be possible to have something similar applied to regular UV map displacement painting.

You may want to try ZBrush or 3D-Coat to see if they handle doing displacement map painting across regular UV seams better than what you are seeing in Modo.

Hi Oskar, I did a bit of digging, and there appears to be plenty of complaints about displacement map painting in Modo not really working as well as it should across seams, here is a discussion thread:

So based on that discussion, I would say you should definitely try 3D-Coat at least and see if you can paint a displacement map better in there, and then just assign that map in Modo instead of doing the actual painting in Modo for displacements.

If that eliminates the issue you ran into with seam displacement artifacts, then you would have a workable general solution set up.


All kinds of models can have UV seams in them, so I don't think just trying to avoid seams is really feasible.

3D Coat has Ptex now.
