This script is very complex, and I will try to find time to understand the issues, but currently, I'm going through a difficult period and am unable to tackle this right now.

When using the transform rig tool to flip a vitruvian bone (the one with the 'V'), it affects and breaks the rigging of the other vitruvian bones that are part of that vitruvian group, because it transforms those other vitruvian bones while leaving their artwork intact, so the bones are no longer correctly placed over the artwork. To avoid this issue, the vitruvian bones need to be ungrouped (deactivating them is not enough) before performing the flip. I tested the rotation too and the same happens.

I wonder if the intention was to make the tool affect every vitruvian bone in the group (but correctly of course), or only the selected one, because I can see how affecting every vitruvian bone could be handy in some cases, however in my case I only wanted to affect the selected vitruvian bone.

I made a quick demo in case you cant to test it. It's just a simple 2 arms Vitruvian group. To reproduce the issue just select one V-bone and transform it with the transform rig tool.

Have a nice day!

Hello! When working with the Vitruvian Bones, the script automatically finds all the bones that are part of the Vitruvian group, but not the layers. That is, all layers with a vector always need to be selected manually.

Changelog:
1. Fixed a bug where, in some situations, flipping parts of the rig caused incorrect adjustments of bone rotations in actions.
2. Fixed a bug where duplicating a bodypart resulted in smartbones having incorrect bone angle animation.

You can bind layers to bones and transform them. If you need uniform scaling, you can use pin bones.

1. Diagnostic Mode
   The Diagnostic mode tab allows you to detect rigging issues such as:
   • Finding and fixing smart bones whose default position does not match the zero frame.
   • Finding layers with transformation and resetting the transformation without visual changes on the screen while preserving all smart bones. You can reset the transformation of all layers in the rig with a single click.
   • Searching for accidentally created bones and curves that overlap each other.
   
   This functionality is needed not only to keep the rig clean but also to ensure that other new features of the tool work correctly.
2. Editing Mode
   The Editing mode tab has the following capabilities:
   • Frame One Editing – lets you transform the rig on the first frame and bake those changes into the zero frame. That is, you can change the character’s proportions, move and scale body parts, edit the positions of points and curvature, and then click Apply Frame One Editing.
     The tool will apply these changes to the zero frame without breaking the smart bones. You can use smart bones to transform the character’s body. For example, rotate a squashing smart bone and bake that deformation into the zero frame.
     To do this, select the smart bone and click Protect Smartbone so that the bone’s position does not change.
   • Advanced Mode from the first version is now called Bones Editing mode and now supports working with points.
3. Transforming Mode
   In the Transforming mode tab, a Smart Unlink button has been added, which allows you to unlink without destroying smart bones.
