The RBC Animation panel records your simulation, either as a rigid body cache or as keyframes on the rig, and exports the result. The rig list at the top selects the active rig. The panel has 2 sections: the Animation Tab and the Export Tab.

• Animation Tab Pin: Pins tab to the RBC Rig > Controls tab, so you can record while you drive.
• Cache/Keyframe: Switches between the Cache and Keyframe modes described below.

Cache

Blender's rigid body cache is a system that stores simulation data for rigid body physics animations.

• It saves the calculated physics simulation data to memory or disk, allowing you to playback the animation without recalculating the physics each time.
• It offers two main types of caching:
  • Scene Memory Cache: Temporarily stores simulation data in RAM.
  • Disk Cache: Saves the simulation data permanently to your hard drive.

• RBC Cache Menu: Menu to manage saved Cache.

  • Scene Cache Dropdown: Drop down list where you can select a different cache. Scene Memory Cache keeps the simulation in RAM; every other cache is saved to disk.
  • Cache Name: Name of Cache.
  • Add Cache: Adds a new Cache saved to disk.
  • Delete Cache: Deletes the current Cache. Note: Scene Memory Cache cannot be deleted.

• Record Cache: A button to start/stop recording the simulation cache, with a progress bar showing the frames recorded. During playback it reads Cache Playback; once the whole frame range is recorded it reads Cache Completed (click it to delete the cache and record again).

• Delete Current Cache: The X button next to ‘Record Cache’ deletes the current cache.

• Pre-Bake Frames: Bakes the set number of warm-up frames (default 24) before the start frame, so the vehicle's suspension has settled when your animation begins. Only available while the cache isn’t baked.

• Bake to Keyframes: Shown once the cache is recorded. Converts the recorded cache into keyframes on the rig's RBC Action, so the animation no longer depends on the cache.

  • Multiple Rigs Toggle: When enabled, the button becomes Bake All to Keyframes and bakes every cached rig.

Keyframe

In Keyframe mode you can record keyframes to your rig while the simulation runs, for example while you drive it with the keyboard or a controller.

• RBC Keyframe Menu: Menu to manage saved Actions.
  • Action Dropdown: Drop down list where you can select different Actions.
  • Action Name: Name of Action.
  • Add Action: Adds a new Action to the rig's Armature. If the rig has no Action yet, the panel shows "Add RBC Action to Keyframe".
  • Duplicate Action: Duplicates current Action.
  • Delete Action: Deletes current Action.
