The FX Tab holds additional effects such as Tire Marks and Tire Smoke to be added to your scene. Effects are added to the active rig, which must be generated first.

- FX Pin: Pins the FX tab to the RBC Rig > Controls tab.
Tire Marks

- Add/Remove Tire Marks: Adds or Removes a tire Mark object for the selected RBC Rig.
- Geometry settings: Holds parameters for the geometry of the Tire Mark object.
- Resolution: Controls the subdivision level of the tire mark object.
- Ground Offset: Sets the height offset from the ground.
- Shrinkwrap: Shrink wraps the tire marks onto the RBC Ground object.
- Material settings: Holds parameters for the Material of the Tire Mark object.
- Image Texture: Image Texture for tire marks.
- Opacity: Controls overall transparency.
- Image/Noise: Mixes Image Texture with a noise texture.
- Pressure: Determines mark intensity for each wheel.
- Slip Ratio: Controls mark visibility based on each wheel’s slip ratio.
- Slip Angle: Controls mark visibility based on each wheel’s slip angle.
- Edges: Controls the softness of mark edges.
- Bake/Delete Cache: Bakes or Deletes the selected RBC Rig’s tire marks geometry simulation cache.
- Multiple Rigs Toggle: When enabled, the button becomes Bake All Cache / Delete All Cache and works on every RBC Rig’s tire marks cache. This is the same toggle as the multiple rigs option next to Bake to Keyframes in RBC Animation.
Tire Smoke

- Add/Remove Tire Smoke: Adds or Removes tire smoke for the selected RBC Rig.
Smoke Domain Settings:
- RBC Smoke Domain: The smoke domain object: the 3D space where smoke can appear. The Eye Icon toggles the smoke in the viewport.
- Domain Size: X/Y and Z dimensions of the simulation area. With the Sync Icon enabled one value sets X and Y together; disable it to set X and Y separately.
- Resolution: Determines the detail level of the smoke simulation - higher numbers mean more detailed smoke.
- Dissolve Time: Controls how long the smoke persists before fading away.
