Seams problem with Displacement

[Teslator]

I have always problems with seams when I use displacement. I tried a lot of different settings but I can't get rid of the seam.
Is there a workaround?

What kind of displacement are you using (just regular displacement along the normal, or 3D displacement)? Which program did you use for the displacement map?

I use 2d displacement but I also tried 3d displacement and had the same problem. The textures work fine without seams they are painted in Mari and the displacementmap is made in Zbrush.
I can upload the displacement map if it helps?

[vlado]

Yes, please if you can get me the model and the displacement maps to vlado@chaosgroup.com it will be very very helpful. One of the developers is looking into this right now, so it will be a very good test.

Are there any news to this problem?

Looks to me like the old problem of seams not lining up in unwrap...unless you use Ptex or unwrap your model so all seams form straight lines, you will always see seams:

At least that´s what I found out and believe me, I´ve been looking for a long time to find an "easy" solution...

Thank you ben this is good to know!

But this seams to be a bug.

[vlado]

Ideally this should be solved by the renderer, yes. Developing a solution will take a while though - this is not an easy "fix"

Ha, glad to hear you see it like that! Because I always thought that was just an inherent mapping problem and thus ADSK´s problem and we all know how fast they are with providing solutions.... I would indeed prefer to get a solution from the rendering side...
I´ve struggled so often with this problem, that I´m using procedural maps instead of painted ones for displacement whenever possible....

Thank you for looking in to it!
