How to merge two vertex groups and add their weights together?

I want to merge two vertex groups in a character mesh to a single vertex group. I have tried many different techniques to solve this, locking vertex groups etc, but none seems to work. Merging two bones was easy, but now I have two vertex groups for example “Bone1” and “Bone2” that I would like to merge and add their weights together.

You can use the vertex weight mix modifier:

you probably want mix mode to be add and mix set to be all. Tweak the settings until you are happy and apply.

No unfortunately, its way too cumbersome method for moving several bone weights to one bone. Any other ideas? Why merging two or more bones can’t just merge the vertex weights too? :frowning:

Any ideas Anyone?

Somebody? :smiley:
