Reset Envelopes

[Anonymous]

I have some bones that during the editing process have been moved around and consequently, their envelopes are now out of place.

How do I reset the envelope of the bone such that it matches the bone's current position and scale?

Hi Zeaufort,

If you've applied a Skin modifier to your object, then you should be able to go into that modifier, select the bone you want to edit, click the Edit Envelopes button and then manually adjust the Envelope Properties (Radius, Cross Sections, etc.) There isn't a "Reset" button per se, but doing it manually should give you more direct control over what the bones influence.

Please let us know if this helps.

Hi Zeaufort,

I wanted to add a note from one of our developers regarding your question:

"If the user is using Envelopes, then the bone is not weighted. To reset the Envelope, please remove and add the bone again. This will recreate the envelope to the Bone position and size as default. (I would agree that there should be a 'Reset' envelope option.)"

You can also re-adjust your envelope manually, as stated before.

I hope this information helps!

This will have to do, it does mean I lose vertex weighting but for some reason my envelopes moved around a great deal while editing the rig so that I was weighting the incorrect bones. Thanks for the answer and yes, a reset button would be much appreciated!

Hi Zeaufort,

I have a better answer for you from one of our developers:

"If the user has some weighting done, and still wishes to reset envelope, he can extract skin data first then re-import after the bone remove-add.

1. To extract Skin data: in ‘Utilities’ panel > ‘More…’ button > ‘Skin Utilities’
2. The Skin Utilities has 2 buttons -- ‘extract skin data to mesh’ and ‘import skin data from mesh’.
3. Extract will extract Skin weights into a new mesh in the scene; prefixed ‘SkinData_’ + the skinned mesh name.
4. The user can now remove and re-add the bone in Skin modifier. This resets the envelope.
5. Once that is done, selecting the Skinned mesh and the ‘SkinData_’ mesh, use the Import Skin data button of Skin Utilities; this will re-import the skin weights.
6. In this workflow, the envelope is reset and skin weights are not lost."

Please let us know if this helps!

I'll be sure to give this a crack when the opportunity presents itself, thanks!

None of these steps fix the problem. I think the issue is with the bones. 

Even adding a new skin then adding bones back to the skin still displays badly scaled envelopes. 

Reseting bones within bone tools still does nothing 

Hard issue to fix.
