Body Colliders
Creates capsule and sphere collision shapes around the actor’s body for physics interaction — used by cloth, hair, and other dynamic parts to bounce off the body instead of clipping through.
Global Size
Size is a master multiplier applied to all collider radii. Adjust this first to match the model’s overall scale before fine-tuning individual regions.
Body Regions
Individual sliders scale specific areas relative to the global size: Head Radius, Arm Radius, Forearms, Chest Width, Waist Width, Hips Width, Leg Radius, Butts Radius, and Belly Radius. Values above 1 enlarge the collider; below 1 shrinks it.
Butts Position and Belly Position shift those colliders in 3D space to match the model’s proportions. Thigh Fwd/Back adjusts thigh collider placement; Thigh Start Position controls where along the leg chain colliders begin.
Visualization
In wireframe physics mode, Visualize renders the collider shapes as translucent gizmos for debugging.
