It looks like you have smooth uv checked in the multi map exporter settings.Try turning it off and also turning it off in the subdivision settings in your render package. I'm not familiar with blender, but it could be 'none' or 'linear' maybe? Also worth checking this…
I don't see seams on lowpoly mesh, it looks like that in Blender viewport for example: Maya and Blender have some smoothing settings for UVs, but in Zbrush I am not sure how can it be. For example I have a highpoly and lowpoly meshes, and I do "projectALL" LP on HP or just copy+paste UVs in UVmaster zplugin if necessary. I…
The result of turning off Smooth UVs setting and turning it off in the subdivision settings in render package: Maya Arnold (AutoBump Enabled) ↓↓↓ (I mean even autobump feature catches these artifacts) Maya Arnold (AutoBump Disabled) ↓↓↓ Blender viewport ↓↓↓ Artifact seams are still here…
I have an artifacts like this after baking displacement in zbrush. There is no difference in the settings I use or 16bit/32bit or format or resolution. When I use SubDiv 5+ on objects with displacement I see this weird stuff on seams, Blender or Maya, doesn't matter. It's NOT like in that video:…
I am using Maya Arnold, but I think it's not a "limitation of renderer" because in Blender the model with displacement has the same artifacts in viewport. In Maya there is a setting "Bounds Padding", but it does noting to render. By the way, thanks for the answer. I did a few more "tests". And I noticed that padding lines…
