Adding a null bone to a skeleton

Post by Lukesmith123 » 06 Nov 2013, 00:00

Hi

I have imported an FBX file that contains a skeleton made up of nulls. I want to add more nulls to the skeleton and assign verts to these nulls.

How can I add nulls to the skeleton and put them in the correct order of the skeletons hierarchy and set them as children of the appropriate parent bone?

And how should I set the verts to these new bones, should I choose reassign locally?

Thanks so much!

Mute your envelope
add a null bone
branch select your null bones skeleton and use Set Reference Pose
unmute your envelope
re-envelope (select your model, use set envelope and branch select your skeleton) to add deformers to your envelope op.
don't check Automatically Reassign Envelope, otherwise your weights will change.
select some points and use reasign locally, or the weight editor to asign weights to the new added null bone.

This is probably a stupid question, but I cant find an envelope to mute in the model.

I'm importing an FBX and there is no envelope property in the explorer.

Also when adding the bone should I set its parent in this stage to one of the bones in the hierarchy?

If it doesn't have an envelope op, then it isn't weighted.
Then the only thing you have to do is add a null to your skeleton, and envelope.
