| mask | The AvatarWeightMask specifying which body parts to include in the transition. |
Sets the per-body-part blend weights from an AvatarWeightMask.
Specifies which body parts are included in the dead blending transition. Body parts in the mask receive full dead blending weight (1.0), while those not in the mask are excluded. The mask is saved internally and automatically re-applied after internal binding reallocation. Float parameters always receive weight 1.0 regardless of the mask.
