Procedural modules

COG

Central controls and body lean.

BodyC

COG controls the body center with Main and Offset, plus an optional Body Lean control.

In Module Manager, choose COG in Module Bank, or its instance in Scene Modules.

1Side 2Body Lean 3Design
COG · CONFIGURATION · Poseidon theme. Body Lean enabled.
Reference Purpose
1 · Side Central module: C only, without mirroring.
2 · Body Lean Adds the Body Lean control. Disabled by default; enabled in this capture. On an existing instance, apply the change with Rebuild.
3 · Design SHAPE selects the shape; COLOR sets each controller’s color. On a built instance, changes apply immediately.

Disabling Body Lean and rebuilding removes that controller. The lean output remains available.

The Main placer defines the COG position. Only translation is editable; rotation and scale are locked.

Controller Role
Main Main controller; drives Offset and Body Lean when present.
Offset Additional adjustment under Main.
Body Lean Optional controller under Offset, driving body lean through the lean output.

In Main’s Channel Box, Show Offset displays Offset and Show Body Lean displays Body Lean when present. These options control curve visibility without disabling their motion.

Ports are central (C) and expose the driver and reference matrix channels.

Direction Port Role
Input base Incoming motion for the COG.
Output main Motion of the Main control.
Output offset Motion of the Offset control.
Output lean Frame for the downstream body. Driven by Body Lean when present; otherwise derived from Offset, compensating for the COG placement.

COG does not create a deformation joint.
