Weight Tags Corrupted?

#1

Hello,
My rig’s Weight Tags have stopped working. I have tried replacing the Skin Deformers, but that didn’t work. I have verified that the weights are normalized and when I hover over the geometry, the vertices are associated with the correct joints. I have tried deleting superfluous joints from the Weight Tag, but nothing has fixed the issue. If I drag the Weight slider from 0% to 100%, the geometry goes to the correct position of the joints, but does not move with them.

If I add a new weight tag and repaint weights, the Skin Deformer works. This is very undesirable though as I have finished weight painting.

These Weight Tags were working previously. What has changed: my rig uses XPresso to disable the Skin Deformers and hide skinned geometry. I tried disabling the XPresso tag and even deleting all of the nodes inside it.

In this image you can see the new weight tag working with the boot of the character, but the pants (which are showing weights from another tag) do not move (the other joints in the image are the FK joints from the Character Object, not the bind joints).

I cannot share the scene file on the forum, but I will PM it to anyone who wants to have a look.

Thank you!

Never seen this. Have you tried exporting the weights via the weight manager’s ‘file’ menu, then replaacing the tag & importing the weights ?

@Decade You were right! Exporting the weights, deleting the old tag, and re-importing the weights to a new one fixed the issue! Thanks for helping me in not having to repaint weights and saving me so many hours. Hallelujah! :smiley:

So glad it worked !
It’s great that they added the import/ export function however many versions ago it was - it’s also really useful for distributing a weighting fix to abunch of animated shots. ie you find your guy has some funky finger-weighting, fix it in the rig file, then import it into all the shots with him in.

@Decade Yes! I am glad to learn about how to edit/fix these tags.

Also worth noting for this thread: I was able to recreate all of my weight tags with a few clicks using these scripts from Bret Bays (for those with Cineversity):

Nice, I have these & for some reason only really use the hammer weights one, I really must catch up on all the others.
His 'Rig-it scripts are good too - especially the split joint & setup FK commands
