I have a character model and a basic human skeleton. I modeled some pants for her. These pants are basically faces from the legs that I duplicated, applied a Solidify modifier, and deleted interior faces for. I decided I need to remake the weights, so I unparented the skeleton, deleted the armature modifier, and redid the automatic weights. But now I have A LOT of weight groups (one for each bone) that I do not need. I want to delete the groups with zero weights (i.e. the hair strands, chest, etc.) I have the pants mesh selected and tried to run Object --> Cleanup --> Clean Vertex Group Weights. with the threshold set to 0.00. But this doesn't do anything.

(note: I tried raising the threshold to 0.01 to see what would happen, but nothing happened.)

Clean Vertex Group Weights does not delete vertex groups, that is not its function. It's supposed to unassign vertices from groups when they've weight below limit. And it does just that.

What @Stan_Pancakes said, the operator removes assignments, not the vertexgroup(s) themselves.

To remove zero-weight groups, you can use a snippet like the following:
https://blender.stackexchange.com/questions/16517/how-to-quickly-remove-all-zero-weight-vertex-groups
I believe there are also Addons out there that provide this functionality.

This isnt a bug though (unless this is a misunderstanding), so will have to close.
Feel free though to comment again if issues persist.
