• Device.Sensor.IMU: Recalculate rotations for the X-axis (pitch) to address gimbal lock issues.
• SDF.Implements: Inertia Tensor Handling
  • Ignored off-diagonal inertia components (Ixy, Ixz, Iyz) due to mismatches with Unity's physics engine.
  • Applied the parent's rotation to inertia tensors to correct rotational discrepancies.
