Turning C0 and C1 into 1 CFrame value

[parkerjolo]

I’m trying to make only the C1 have values inside of it in order to avoid this awful problem where rotated accessories will go around their attachment point (like in the attached video), but I just can’t figure out the CFrame math associated with it.

How would I go about doing this? Everything that I’ve tried so far has yielded mixed results, with some working for only some accessories, and others just not working at all.

motor6D.C1 = motor6D.C1 * motor6D.C0:Inverse()
motor6D.C0 = CFrame.new()

For an example of solving a CFrame equation (although a different example than this situation), see this post:

No, C0 is not the CFrame for Part1 relative to Part0 unless both Transform and C1 are identity matrices. The CFrame of Part1 relative to Part0 is Part0.CFrame:Inverse() * Part1.CFrame. By solving this expression from the equation in my answer above we can get an expression for this relative CFrame in terms of C0, Transform and C1. The equation: Part0.CFrame * Motor6D.C0 * Motor6D.Transform = Part1.CFrame * Motor6D.C1 We can think of each side of the equation as a single matrix (which is the…
