hey folks right now I try to render a simple sphere in Arnold with a displacement map, it kinda works, it looks like that: zbrush: Maya: Maya closeup (this is where the error is visible): it looks very weird and i dont know what i did wrong here: i exported the mesh from subdivision-level 2, and the displ.map was generated…
Go one subD level higher. 3 might not be enough. And its possible that a 8k map is on its limits. Take a close look if you see the pixels there. And export the highres sphere for rendering in Arnold to compare to the right thing. Rule number one. Dont trust Zbrush.
