To share animations between all characters in your application, what Animation Type should each character's rig be set to?

When sharing animations between characters in an application, setting each character's rig to Humanoid is the most effective choice. The Humanoid animation type is designed specifically for humanoid characters, allowing for the use of a shared set of animations across different character models. This is possible due to the standardization of bone structures that the Humanoid rig employs, which ensures that animations are compatible with any character that adheres to this structure.

The advantages of using Humanoid include support for advanced features such as retargeting, which enables the application of animations from one character to another regardless of slight variations in character proportions or rigging details. Humanoid also supports features like blend trees and avatar masks, enhancing animation flexibility and allowing for more dynamic character control and smoothing transitions between animations.

In contrast, other animation types like Generic are more suited for non-humanoid characters or custom setups where bone structures may differ significantly. Legacy might refer to previous systems and lacks the advanced features and flexibility of the Humanoid system. Custom animations would typically require a unique setup for each character, making them less suitable for sharing across multiple characters. Consequently, Humanoid is the optimal choice for maximizing animation reusability and efficiency in character design within a game development context.
