Member hello Posted June 26, 2017 Member Report Share Posted June 26, 2017 Hello, I have hi-poly model of the car, I need to make UV map to be able to import it to UnrealEngine. Currently, I have the model, but I made a mistake and forgot to check SeparateUV for each material and it made me everything in one UV. This way I have exported OBJ file and imported back to 3D-Coat and tick "Separate UV for materials" (don't remember the exact name), so now I have to go through each UV material and click Unwrap to re-unwrap this uv again, basically it just scales what I have before. Is there any way to click Unwrap All and it will go to each UV map and just Unwraps it? How about that? Thank you. Quote Link to comment Share on other sites More sharing options...
Member hello Posted June 28, 2017 Author Member Report Share Posted June 28, 2017 I see no way to do it, also there is annoying bug when I can't work with separate UV, only imports everything into one UV, such a glitch! Quote Link to comment Share on other sites More sharing options...
Carlosan Posted June 28, 2017 Report Share Posted June 28, 2017 Use Fbx file format to avoid it Quote Link to comment Share on other sites More sharing options...
Member hello Posted June 28, 2017 Author Member Report Share Posted June 28, 2017 I'm, only using .fbx format, do you want me to share you the file? Quote Link to comment Share on other sites More sharing options...

Member hello Posted June 28, 2017 Author Member Report Share Posted June 28, 2017 This is a test file, when I importing this .fbx to 3D-Coat and checking "Treat materials as separate textures" and I see list of materials then I click Okay, it's performing auto-map, when I want to switch to other UV, there is no other UV, they all got collapsed into one UV. It been happening 99% of the time. I don't want to have one UV, I want to be each UV unwrapped to 100% of the space, not to only UV-space (single UV map for the entire project), I don't need that. Please review. http://dropmefiles.com/d8jAw Quote Link to comment Share on other sites More sharing options...
Carlosan Posted June 28, 2017 Report Share Posted June 28, 2017 auto-map only generate one UVmap. You must to use KeepUV 1 Quote Link to comment Share on other sites More sharing options...
Member hello Posted June 28, 2017 Author Member Report Share Posted June 28, 2017 Oh okay, that makes sense, I'm sorry I was misinformed by this option, still a bug to me. What I want to do, auto-map all UV maps separately, I hope they can make this feature in the future updates. Thank you. Quote Link to comment Share on other sites More sharing options...
