Monster Truck Rig (Rigid Bodies)

A Moonster Truck Rigged with Rigid Body Physics.

Rigid Body Interactions!

Drives with Drivers!

Blender 3.0 Recommended

Just a helpful heads up, Blender Rigid Body Physics aren't flawless, these are just some of the issues and fixes I've found while working on this project

1. Enable Undo Legacy

   For some reason, Rigid Body Constraints can cause undo to crash blender so I'd recommend Enabling Undo Legacy in Preferences under Experimental.

   

   
   

2. Keep Rigid Body Collections Enabled

   Keep Rigid Bodies Rig Collections enabled in order for the rig to work properly.

   

   
   

3. Ghost Bodies

   I find this happens when you delete a Collection of Rigid Body objects and not individually, but If the truck is acting weird like interacting with things that aren't there check the Orphan Data panel.

   

   
   

   
   

4. Rigid Body World Settings

   I'd Recommend building within the blend file itself but you can still append the truck under the collection name Monster Truck to your own file.

   After appending set up the Rigid Body World, make sure the constraints collection is enabled and the solver iterations are close to about 30-50.

   

   
   

5. Cache Issues

   Sometimes I've found the Cache doesn't reset so I just move a ground(any Rigid Body object) then snap it back into place to quickly reset the cache.
