Blaze

Blaze Animate - Click & Drag Animation brings click-and-drag animation to Blender, letting you select and manipulate rig controllers directly in the viewport instead of searching bone hierarchies, with smart selection tools and visual feedback.

Blaze Puppeteer is a Blender add-on for motion generation directly on your rig. It offers direct FK/IK on any humanoid rig without retargeting, inbetweening via anchors, and root motion steered with waypoints and dense paths.
