Maya, V-Ray - Weirdness on mesh when render with height maps

Finardi

Hi!
I recently posted this topic which has been quite solved already (https://polycount.com/discussion/226562/displacement-seams-gaps#latest) about displacement map visible gaps. But my mesh is also marking on some edges regions, which have nothing to do with the seams anymore, they do not coincide. Here are two of these places where it appears:


I believe it's something to do with the mesh normals, or the smoothing groups, but I've already recalculated the normals with 'average' and 'from faces' and no difference has happened. It's only happening in a few areas and they represent edges, not UV seams. Has sdy gone through that already?
Thx!

Is there a normalmap on top?

Finardi

Yes, normal and displacement.

In this case i would say the normalmap isnt in the right colorspace. It has to be raw.

Finardi

I turned to raw already. Idk man, such a pain dealing with these maps! Hopefully in the near future people will start adopting Unreal's workflow.

Unreal isnt different for animated meshes. And for stills we render highpoly meshes in Maya. 

Finardi

This has never happened to anyone? ZBrush > Maya (V-ray) workflow.
I have one displacement and a normal map applied.

There is a reaon why many studios bake displacements in Mudbox.

As mentioned in the other thread your basemesh has to be dens in curvy areas. Try to bake onto level 2.

Ok, thanks!
