I got an access to MudBox just for testing Displacement export from another app. Firstly, I baked 16px padding VS 128px and there were no seam artifacts on both. Then I noticed that when I'm baking with "Smooth UVs" turned off in Zbrush, on the model appears other artifacts along the low poly mesh (wireframe), like that:…
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…
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…
Different applications use different techniques to calculate the padding. If it looks a little different in the empty space this is unlikely to cause any problems. Generally, Eric's advice makes sense but the padding distance applies more to when the textures are viewed from a distance at lower mipmips. At mip 0 this…
