What is the difference between a Humanoid avatar and a Generic rig in Unity, and when would you use each?

• A. Humanoid avatars cannot be used for human characters.
• B. Generic rigs are used for non-humanoid skeletons.
• C. Humanoid avatars support retargeting across bipeds; Generic rigs are for non-humanoid skeletons. Use Humanoid for human characters.
• D. Humanoid avatars have no difference from Generic rigs.

Answer: (C)

Humanoid avatars use Unity’s standard human bone structure, which lets animation data be retargeted between any characters that share that bipded skeleton. This means you can create a motion on one human and drive other human characters with different proportions using the same animation clips. That cross-character reuse is the big benefit for human characters. Generic rigs don’t follow a universal human skeleton, so animations are tied to the specific rig you set up. They’re ideal for non-human or nonstandard skeletons (animals, monsters with unusual bone setups, or mechanical rigs) where you don’t need broad retargeting. So, you’d choose Humanoid for human characters to enable retargeting, and Generic for non-humanoid or custom rigs where universal animation reuse isn’t applicable.
