Made plenty of tests before reporting.
Can’t tell wether it’s a Nomad or Procreate issue.
A simple plane trimmed in Nomad (hole filling off), generate UVs with Atlas method and export to OBJ.
Import to Procreate, paint, export to Nomad.(keep topology ON or OFF with same result)
These are some results with always same workflow.
I had the same problem. With a PLANE sometimes the thing does not work. I also tested a lot, sometimes the UV is mirrored or twisted…
I tried to create a picture frame with canvas for Procreate - with aligned UV to canvas, so that in Procreate the 2D texture works in the right alignment.
With the PLANE it somehow doesn’t work properly either way.With an extracted Side from a Qube it works better than with a PLANE.
