Non-skinned Mesh Animation

CPU Animator

Rukhanka Animation can animate arbitrary Entity hierarchy. The process is essentially the same as for ordinary skinned meshes:

• Create animation clips that target transforms in the hierarchy and reference them from an Animator Controller.
• Place the hierarchy in an Entities SubScene and add Rig Definition Authoring to its root.
• Add a Unity Animator, assign the controller, and set Culling Mode to Always Animate for the initial setup.
• If no Avatar is assigned, Rukhanka Animation builds the rig from the transform hierarchy starting at the object with Rig Definition Authoring.

GPU Animator

• Follow the same preparation steps as for CPU Animator.
• Make a GPU attachment shader and set it for materials of your attached render meshes.
• Add GPU Attachment Authoring to each affected mesh as described in Bone Attachments. GPU animation changes rendered vertices without updating CPU transform data.
