hi to all of you after a long time!

I need a realistic looking rough leather material and started building one in the test scene. I am quite happy with the look and the displacement gives nice results in terms of the roughness.



Now the problem: As soon as I apply the shader in the same scene to another geometry I only get bad results. I understand that the geometry detail has its influence on the displacement, but the geometry detail level looks quite similar...images look superblurry and turning adaptive precision on results in endless rendering...

Thank you for any advice and cheers out of rainy tokyo

how far away are you viewing the material from in your scene. If its not macro I would turn displacement off.

If you could post some examples.....probably best is to turn on absolute height when you're creating the material, this way the size of the geometry you're applying the displacement material too won't matter.

thank you for your advice deflix and mihai.

I need to render macro shots and the material look is key so I guess displacement is the way to go here.

Even with the absulute height value constrained the pictures look so different to the test shot. I cleaned up the uv map so there the problem should also not be....

some results




this is the reference material which I scanned in for the diffuse map

It looks already pretty close, try increasing the abs height a bit more.

Can you show us a wireframe? I would like to see how your mesh is subdivided.
