There are multiple cases have been reported. I cannot be sure about the others, but in my case, I have exported to FBX, Imported to Blender and got texture mismatch. Essentially it was caused by pulling the texture from a wrong export in my case. It was an OBJ export folder, which I exported a few days ago with older Base.
I cannot replicate this bug anymore though. It is obviously a bug/glitch, where some texture path is hardcoded somewhere and then used randomly in consecutive exports. Please see the screenshot and this post for little more details: https://forum.reallusion.com/FindPost454898.aspx
Thanks for your feedback!
Could you send your OBJ with mtl to us?
You can upload to cloud service such as Google Drive, and attach the download link in your next comment.
Also, do you have other 3D software such as Maya / 3dsMax / 3DXchange, could you import OBJ to these software to see if the texture still wrong?
Thanks for your help!
Here is another example. I just exported a default CC3+ female as an FBX and I got a texture from "FIXING_BRAIDS" folder. This folder was the OBJ export I did days back, when working with a a girl for a competition. Pls. see screenshot.
I just converted the male character to 3.3+, and the problem persists! Manually relinking map still doesn't work!
