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.
