importing for retexturing issue

Greetings!

The workflow:

  1. align - mesh - color -texture - save - export (obj, rc info)

  2. in Zbrush: duplicateing the high poly mesh - zremesher on duplicated - subdivision the zremeshed with projection from the original in every subdiv step - splitting the zremeshed object to polygroups - UV generation - exporting and saving the OBJ on the same name as the RC_info file.

  3. importing the retopoed, UV’ed obj to RC saved scene - (the position seems ok) - reprojecting the texture - the end result seems blurry and off from original position (see: the object has 2 nose and extremely blury texture in some parts)

I tried photo-consistency and olso visibility based texturing - same result

I tried 4k, 8k - same result

 

I would need some help please.

two more images to see the “sharp” and “blurry” contrast:

I guess I figured out the issue:

  • if we use smooth brush inside Zbrush it will basicaly not just smoothing the surface till cleaning the scaned mesh, but also changing the shape of it.

If anyone can give me some suggestions, information due to this issue, please share, even if it seems that (due to an actual test scenario) I solved it. But I can imagine that my issue could be generated by many sources. So please share if you meet or solved simmilar situations.

I made some tests and this is an olready rendered out test image by Arnold in Maya after Zbrush cleaning, retopo + UV and substance baking maps from colormap:
