I was trying to simulate a steering rig using bones but I kept running into difficulties with the TrackTo modifiers and the space in which they operate.
Since I have a single armature, which has the same alignment as the global space, I expected all the modifiers to behave the same in local as in world space.
This is not true and I am unable to figure out how I should interpret the spaces which are selectable in the various modifiers.
I’ve uploaded a file to illustrate my problems:
The idea is that when you rotate Armature.Bone along it’s local Z-axis, all the other parts move along.
This works somewhat, but only because I’ve set the trackTo mods to pose space. If I set them to Local space, the whole rig goes crazy… Also, I expected all the rotations to happen at the Y-axis, but this too seems to be invalid…
If someone could please enlighten me on what is going on exactly, it would be much apreciated
