Car Rigging Part 5 - Wire based Tire Pressure

Final Setup Demo

Recently i was asked a question on a forum I'm a part of, if there was any alternative methods to Ant CGs amazing tire pressure tutorial, which if you haven't already seen stop reading this right now, and go watch it is probably a lot more stable and well thought out. Ant CG video - Joint Based Tire Pressure: https://www.youtube.com/watch?v=CFWWdNuawfc However after throwing this together i thought it might be worth showing this alternate deformer based method with my favourite "Friend and Foe" the dreaded IK spine curve. Its pretty simple setup, Im using a IK spine joint curve to drive the joints, and a wire that is deforming the ik curve shape. Then for some somewhat lazy deflating effect im blend shaping the curve, which if you have followed me if a favourite trick of mine. When the blendshape is at 0 it is fully inflated no pressure applied.

When it is pushed down the blendshape turns on.

That pretty much the setup. As usual reach out if you have any questions. Happy rigging. Jase
