Fabrik Leg IK World Space to Object Space

[rocky bough]

Hey everyone,

While making a quadruped leg IK. I found out that bones have a woldCFrame. I use this to make a comparison of the distance between the target (different CFrame) and the bone I want to move.

The problem is that I do not believe I can set the bone's worldCFrame. Does this mean I need to make the calculations for each bone down the bone chain until I get the one I want or is there something else I can use to make this calculation.

P.S. I have already tried :ToObjectSpace(). This generates the wrong numbers from the CFrame.

Thanks!

Convert the Target's CFrame to local space, then perform IK calculations and then update bone positions

Okay, so ya the conversion does have to be done manually

thank you

Oh, I go from target to bone because then I only have to do it once!

hi, since this post was already there, i thought i'd take this chance to ask you,
im trying out the inbuilt ik function and i am having trouble making a custom model and adding ik to it, do i need to add bones or servos?
thank you so much for reading.
