polyMoveUV node in Maya 2020 is broken

[george.sladkovsky]

Hi everyone!

So I'm pretty sure that polyMoveUV node is broken right now in Maya 2020

When you open a project with this node from previous versions of Maya, or even save and reopen the project from Maya 2020, this node stops working completely. The issue here is that inputComponents list is saved in a weird way for some reason.

This should say map[*] and not nmm[*]

But even if you fix this using a script. Next time you reload the project it will be nmm[*] again.

Any Ideas what's going on? Is it a bug or polyMoveUV functionality was changed somehow?

Hi!

I can't reproduce this problem here with Maya 2020.1 .

Here is a quick video to demonstrate the bug:

And here are the steps to reproduce it:

1. Open fresh scene

2. Add any geometry

3. Apply polyMoveUV command (and node) to this geometry

4. Change attributes of polyMoveUV node

5. Save and Reload the scene

6. Node and its attributes are now ignored

Hi!

Ok now I can reproduce this, but here some more details:

1. This is not a problem of saving, the saved file is OK.

2. This happens only when loading the scene in Maya 2020.1

and

3. Maya 2020.1 only shows the problem when loading an ".mb" file,

".ma" files still load fine.

Please report this problem (bug?) to Autodesk.
In Maya main menu:
Help -> Speak Back -> Report a Problem

Yep, I reported it as soon as I discovered it. It's now up to Autodesk to fix this.

Echoing this, - please update with a fix in next version. 
Very frustrating and thanks @george.sladkovsky  for finding a solution for now

Just echoing the above - just stumbled upon this myself trying to "rig" some UVs - broken in 2020.1 ... I reverted to 2019  and it seems to be working fine there (cant see any mention of polyMoveUV in release notes for later 2020 patches so assume its still not fixed)

[george.sladkovsky]

Yes, it was not fixed as of Maya 2020.4, as far as I can tell.

If someone can report this issue to Autodesk, please do. Maybe it will be noticed then.
