I’m trying to do this without adding a python script to the scene unless it’s contained in a driver. Every Blender tutorial I’ve seen on wheel turning matching movement assumes the vehicle is going in a straight line on a single axis. Not a single one that I’ve found passes the “U-turn test”. ((dri…

Thank you, I got it and I understood how it worked immediately. It’s kind of the simplest possible solution with the main disadvantage happening when working on a production where they do the vehicle rigging and hire the animators later. I suspect animators would prefer to just move and rotate the v…

[image] StephG: I’m really trying to avoid another python script in the scene if possible Why? So @DNorman post references a Stack Exchange post by @batFINGER , and he really knew his stuff well. So I am sure batFINGER’s advice is spot on. Another user who was good at this stuff was @clockm…

[image] revolt_randy: post references a Stack Exchange post by @batFINGER The stack exchange thread does not really talk about wheel rotation, it is more about moving bones along a curve in a snake like fashion, for trains, trailers to follow behind. A side effect is that you can use the met…

It’s one thing when I’m in the same building with the people I work with, and another when we’re not only remote but the animators might not use the rig for weeks or months after I’ve moved on. So making features dependent on a Python script adds a major point of failure. It means an animator broug…

Gonna take a look at the Launch Control stuff later this week. Thanks for the suggestions!

Got a notification from this thread and couldn’t help but speaking into it, heheh. Yes, Launch Control is indeed a spline based workflow. It’s not a simulated solution though, but an animation tool - By that I mean that it favours the animators creative judgement rather than relying on a full simul…

[image] Dan80: The rig uses Ackermann steering :rofl: Yes my example was like a go cart. I used it for a traction engine that rotates the axel. I even managed to get a differential value with extra perpendicular bones (not in the example file I linked). You could adapt it to Ackermann. You…

Quaternions are what will keep your wheels always running in the same direction. I’m assuming that you are trying to make a curve where all wheels rotate individually without slipping or have the need to fake using keyframe animation. Maya has a script for that called makeRoll that has some very com…

This makes me feel a bit silly, It has been a while since I tried doing this with the follow path constraint. It does work. Simply animating the offset and using that as a driver for the wheels rotation! Here the wheels are parented to the plane, the plane follows the path, I animate the offset a…
