Textures after merging is incorrect

Support & Feedback

Hello, I 'm new to Revopoint’s 3D scanner.
After using the RevoScan merging, the texture on the mesh didn’t match as expected.
Only those single scans having correct texture. In the RevoScan it’s showing the merged texture correctly, however when exporting in any format. The texture doesn’t match with the new UV map on the merged model. May I know will there be a patch coming to fix this issue?

Hi @crossvadar

You exported Textured model as OBJ and it has different UVs than texture map ?

What version of the software you are using ?

Only OBJ support UV /Textures
Let me know .. you should have exported OBJ , Textures, MTL files
After exporting.

Hello there,
I’ve tried OBJ and other formats, exported the merge model to Blender.

I’m using the RevoScan Windows V5.5.3 with Blender 4.4.1.

I have exported all model formats that RevoScan has, none of them have matching UV mapping for the exports. OBJ also has a mismatched UV Map on it.

I will check it out today to see what is going on and if another bug.

Is there any fixes or steps I have to do?

Did you edit the original scans after merging? Frame Edit Mode can alter the original scan files which might mess up texturing merged scans that reference them.

Hi @crossvadar there is no bug in the last public version of RevoScan software and everything working the way it should , the textures are exported the proper way after merging , meshing and texturing.

Now what your problem is the software that you try to import the model after , it flips the UVs upside down , so you have 2 choices , you flip the textures vertically and load it to your 3D software, or you flip back the UVs in your software vertically and load your textures

Programs like Zbrush for example need the textures or UVs to be flipped vertically also to make it works correct on the model. Remember not all exported extensions support UVs maps and textures , so stick to exporting as OBJ for best results.

Not big deal , you can fix it in seconds

Here the proper steps

  1. Scan your model , both angles 2-3 as needed
  2. Fuse the scans one by one and clean them
  3. Open Merge tab and merge the scans together
  4. Clean the merged scan after merge
  5. Mesh the merged scan
  6. Create textures
  7. Export textured model as OBJ ( you get 3 files, MTL, obj and jpg
  8. Import the model to Blender, if textures are flipped, flip vertically the textures or the UVs of the model . Done

Remember OBJ is a rich model format that is supported in Blenders, the model will not only include RGB color per point data ( color per vertex) but also UVs .
