Like Blender, PixCap is free to use for the editor features. But PixCap is also significantly easier to learn than Blender and entirely focussed on delivering character body animations, which are used across 3D games.
PixCap's overall UI and hotkeys are also very similar to Maya, and more similar to Unity than Blender.
Finally, PixCap's main feature is AI motion capture integrated with a complete animation editor, which allows 5x speed ups in animation times compared to Maya/Blender.
