Deleting UV set in Maya 2017

[buffaloe]

I'm trying to delete an extra UV set in Maya 2017 (I'm on update 4) and am seeing some very odd results.  When I right click and delete the uv set in the uv editor, sometimes it just renames it to something like this one:  ___delete______delete______delete___uvSet_________

Any idea what might be going on here?

Hi!

I'm not sure what causes this, but i found a bug that may be responsible for this: When deleting with right-mouse click the internal Maya command misses quotation marks for the UV Set Name.

Maya creates:

polyUVSet -delete -uvSet test_uvSet_name

instead of:

polyUVSet -delete -uvSet "test_uvSet_name"

this can lead to problems in some cases (based on the naming of the UV Set):

Please report this problem (bug?) to Autodesk.

Interesting.. I've been having all kinds of issues with UV sets so this might help, thanks!

And I would love to report this with Help -> Speak Back -> Report a Problem but when I do that, I get an error saying Windows can't find IExplorer in every version of Maya I've used, so I just don't use it.  😕

sorry If I'm not allowed to bump old threads but I'm currently having this same exact issue in version 2019. If this is still a bug I can't believe this was never removed. Is there a fix for this?

Hi!

Please provide the steps how to reproduce this.

I can't confirm any issue related to this for Maya 2019 or Maya 2020.

Copying UVs to other sets and deleting uneeded UV sets will cause additional sets to appear named "___delete__delete___"UvSetName"____".

 I can delete them and they'll just reappear or it'll trigger UV sets on other meshes to completely break or disappear.

Hi!

The exact steps are required how to reproduce this with a fresh scene or a scene-file if this is a scene-specific problem.

For now I can't confirm this.

I recommend to try a reset of your Maya Preferences
Rename the folder prefs in folder 2020 to something like prefs_backup, or the folder 2020 to 2020_backup
(Don't copy preferences from previous Maya versions.),
or for a complete reset of all Preferences, rename the maya folder to maya_backup.

Deleting preferences didn't do anything but exporting my entire project via fbx into a new scene has seems to fix the issue for now.

Hi!

Then this is a scene-specific issue and the export import process acts as some sort of filter that removes the problematic element(s) from the scene.
