A quick update on "Maya 2020 and 2020.1" UV Bug and CurveTools

Only for Maya 2020 users!

It seems that this issue only affects Maya Binary file type (.mb) and not Maya ASCII file type (.ma

Until Autodesk fixes this issue, please try to use only Maya ASCII project files for your hair projects.


1. Open your Maya Binary file 

2. Apply the "Fix Old UVs" fix in the Options Menu of GS CurveTools 

3. Save the scene as Maya ASCII using "Save Scene As" 

4. It should now work perfectly fine 

Maya ASCII opens kind of slow, at least for me, but it should at least work properly. 

P.S. And that’s why you never update to a latest version …
