3D Physics (Jolt/Native)

Expert guidance for high-performance 3D physics and ragdolls.

NEVER Do

• NEVER scale RigidBody3D — Scale collision shapes, NEVER the body itself. Non-uniform scaling breaks physics engines logic.
• NEVER use move_and_slide inside _process — Always use _physics_process. Frame-rate dependency kills simulation stability.
• NEVER simulate ragdolls 24/7 — Only enable physical bones on death or impact. Animate static meshes otherwise to save CPU.
• NEVER ignore Jolt — Godot Jolt plugin is strictly superior to default Godot Physics in 4.x for stability and performance. Use it if possible.
• NEVER use ConcaveCollisionShape3D for dynamic bodies — Concave shapes (Trimesh) are for static ground only. Moving bodies MUST be Convex or Primitive (Box/Capsule).
