This article is intended to explain the workflow of using the [http://mods.oni2.net/node/388 Rigify-based animation rig for Blender] (made by geyser) for the purpose of making Oni animations, and also how to use it, and what are the Oni-specific additions to it that we've made. | This article is intended to explain the workflow of using the [http://mods.oni2.net/node/388 Rigify-based animation rig for Blender] (made by geyser) for the purpose of making Oni animations, and also how to use it, and what are the Oni-specific additions to it that we've made. | ||

The way we do animations is we almost universally start by copying the first or last frame of the preceeding animation. For this reason, we needed functionality that would allow us to snap the rig to an animated Oni character. The way it works, it that it uses bone constraints in rig controller bones targeting the character model in order to snap the rig to the model. The influence of the bone constraints is controlled through the Z location of Pose1 and Pose2 bones in the Pose Matching layer, which is done through drivers. | The way we do animations is we almost universally start by copying the first or last frame of the preceeding animation.

Often when using the IK handles for the arms you will find out that most of the time, you will need the hand to have the same rotation as the forearm. Normally this would mean that you would have to rotate the hands all the time, because IK handles are mainly moved around, and rotated later. For this reason, the wrist snapping functionality was implemented - you can simply copy the rotation of the forearm to the hand by pressing the "IK wrist" button. | Often when using the IK handles for the arms you will find out that most of the time, you will need the hand to have the same rotation as the forearm.
