Thank you for your help, Martin. I have the animatic looking the way I want, even though it’s not as physically elegant as the original. All I have to do is fit my bulldozer model into the animation.
Your suggestions that I use a path collider with a transparent material, that I lower the friction on the collider and tractor, and that I increase the weight of the shards really helped me dial in the animation.
To finish this topic and clean up any loose ends, here’s the animatic and my tractor setup and rigid body settings:
I can’t parent two rigid bodies to each other, but I can parent two rigid bodies to an empty!
Tractor rigid body settings:
Path collider rigid body settings:
Shard rigid body settings:
Once I add the bulldozer model, it’ll probably need more tweaking. I’ll post the end result once I finish.
Thanks again!
