CloudRig

New stuff:

• Context-sensitive rig UI
  • Optional and off by default for now.
  • Deselect all bones to see full UI.
  • Feedback welcome; If you feel a slider doesn't appear when you'd expect it to, feel free to open a report.
• In Wireframe shading view, the rig preview overlay now draws with x-ray.
• Spine: Cartoon component's custom property settings were exposed.
• Aim component now propagates its rotation locks to the control bone.
• Implement #301: Allow specifying property storage of Single Control component. Only affects the parent switching property, not Custom properties on the bone itself.
• Metarigs and samples now use "World Align Controls" instead of deprecated "Flatten Controls".
• Sintel metarig now showcases parent switching set-up on her eye components.

Fixes:

• Fix Parent Switching on Aim components would only work if it was assigned to the last component in a given "Aim Group".
• Fix corrective actions on a metarig saved in blender 5.0 not working on blender 5.1. This is a one-way conversion, so going back to 5.0 will break corrective action references.
• Fix Spine: Cartoon error with BBone Density of 0.
• Fix #317: Pole Target object of IK constraints not remapped from metarig to target rig (with Raw Copy).
• Fix #314: Curve modifiers not always removed on re-generate, resulting in accumulation.
• Fix #315: Properties UI editing pop-up not clearing prop_name when selecting a bone/collection
• Fix Raw Copy components were using Root Parenting/Parent Switching, despite not displaying their UI. They now no longer inherit this behaviour.

Bone Display Fixes:

• Fix custom shape scale operator (Alt+Shift+S) goes crazy with symmetry when bone has no opposite.
• Fix custom shape scale being incorrectly calculated in some cases, most notably for STR- controls after being symmetrized.
• Fix #312: Bone shape versioning for pre-4.5 metarigs failing on Bone Tweak/Raw Copy.
• Fix #312: Versioning code was unnecessarily running for armatures that started out as a Single Bone armature. Most notably, this was causing custom shape scales to get messed up after a save and reload.
• Fix Bone Tweak component not affecting new "Affect Gizmo" and "Use as Pivot" properties.
• Fix length of IK controls not staying consistent with Flatten/World-Align params, affecting size of the IK bone shape.
• Fix Forefoot control's shape on leg component was not customizable.
• Fix #318: Duplicate IK Master not displaying correctly with World-Align
• Fix Spine: IK/FK component's chest control displaying with incorrect rotation when using World-Align
