Weight Tags Corrupted?

Recommended Posts

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).

Is this a bug or does anyone have suggestions for how to get these Weight Tags working again? Thank you.

    Hi @Rectro,

    Thanks for the reply. I cannot share the file on the forum I'm afraid. I tried sending you the file in PM, but I see you cannot receive messages. Is there another way I can send this to you privately?

     

    Thank you!

    Updating this thread with what fixed my issue:

    Dan very wisely suggested exporting the weights and re-importing them. I had to:

    1. Save the Weight Tag's joint selection with a Selection object
    2. Save the weights from the corrupted Weight Tag (from Weight Manager's File menu)
    3. Delete the corrupted Weight Tag
    4. Create a new Weight Tag
    5. Re-select the joints with the Select object
    6. Add them to the new Weight Tag
    7. Load the weights (from Weight Manager's File menu)

    It's a lot of steps, but this worked! It's a LOT faster than having to repaint weights for all of my characters using this rig.

    Thank you, thank you, thank you @Rectro for going above and beyond! You helped me a lot.
