Rotation Force in Cinema 4D applies rotational torque to dynamic objects, causing them to spin or rotate in simulations. It is used to add rotational motion and angular velocity to particles, rigid bodies, and other dynamic elements.
What It Is
- Rotation Object: A force that imparts rotational torque to objects in a simulation.
- Influences the angular velocity and spin of particles and rigid bodies.
- Supports directional control over rotation axis and strength.
- Can be combined with other forces for complex dynamic behaviors.
How It Works
- Create a Rotation force from the Simulate → Forces → Rotation menu.
- Position and orient the Rotation force object in the scene.
- Set the rotation axis (X, Y, Z) and strength parameters to control spin direction and speed.
- Apply the Rotation force to dynamic objects such as particles or rigid bodies.
- Use fields to limit or vary the rotation effect spatially.
- Play the timeline to see objects spin and rotate under the influence of the force.
Use Cases
- Adding spin to particles in a dynamic particle system.
- Simulating rotational forces like turbines, fans, or wheels.
- Enhancing naturalistic motion of debris or shattered objects.
- Creating swirling or twisting motion effects.
Benefits
- Easy to add realistic rotational dynamics to objects.
- Adjustable axis and strength for precise control.
- Works with many simulation types including particles and rigid bodies.
- Combines well with other forces for rich dynamic behavior.
