Game Deformation Guidelines

Harmony can export deformations to the game engine XML format. Only hierarchies made of Game Bones can be successfully exported. In addition, Kinematic Outputs were implemented to complement your game bones.

Deformations in Harmony come with a wide set of features. However, some of these features are not compatible with the game engine SDK and must not be used for gaming. Hence, Game Bone deformers do not support the following standard Bone deformer features:

• Zones of influence
• Curve and Envelope deformations
• Having more than a single pose in the deformation hierarchy
• Animating drawing pegs underneath deformation groups

The deformation in the game engine SDK does not behave exactly as the Bone deformation in Harmony.

To comply with most game engines and maintain fast calculations, the SDK implements a linear base skinning algorithm to blend the bones at articulations. You may notice some differences depending on the curvature of the articulations used. That said, compared to regular Bone deformations, GameBones most closely resemble in Harmony what you will see once imported to Unity.
