Blender 3.2.1 - Animation on nodes gets bugged out when dealing with Node Groups (duplicate node names) #101109

System Information
Operating system: Ubuntu 21.04
Graphics card: GTX 1080

Blender Version
Broken: 3.2.1
Worked: 2.79

Short description of error
Animation on a node, that then gets put into a node group, effects other nodes later on

Exact steps for others to reproduce the error

  1. Open attached blend file
  2. Make sure you have blender 2.79 hotkeys otherwise i dont know if this will work 100%
  3. in the material editor, press ctrl g to add it to a node group
  4. press tab to exit out
  5. shift a -> c -> m (add mix node)
  6. drop it between the node group and the hue sat value node
  7. scrub the timeline

Expected behaviour
New node does not have a animation applied to it
materialAnimationBug.blend

note that the issue goes away after saving/reloading (so in this step the borked animation paths seem to be cleaned up)

That's quite interesting, it actually affects the result, so it's not just UI glitch...

Yep, and whats more crazy is that the element thats animated, is not highlighted yellow / green

There is something wrong in interpreting that FCurve path.
Since this is name-based, blender somewhat gets confused because of that "duplicate" name (both nodes are named "Mix.001" - only one is inside the nodegroup, the other one not...)
If the "failing" one is renamed, the issue goes away on it (it is still preserved on the "working" in the nodegroup.

On a side-note: Just realized that if a node has animation (such as the Factor here) and it gets grouped, the Factor is then noodled up to the nodegroup (which is generally a good thing -- issue being that the effective animation on the node is now disabled, since the Factor on the nodegroup itself is not getting the animation transferred over).
Will report that separately though.

@candreacchio : is that what you meant with the following?

Factor colour i was commenting on

Following on from this, if you instead of adding in another mixrgb node, you rename the Hue Sat node to Mix.001, it will animate the Hue 0,1 and not the factor.

The animation gets unlinked if you save / revert the file. However, it is not an ideal workflow.

I have also had duplicated objects be effected similarly previously (where trying to make unique animation, doesnt actually make it unique animation) and the only way to fix it was to save close reopen, but unable to replicate it like this instance.

Same is true for Geometry nodes as well
