CFrame of Part relative to Motor6d

[JavaCompiled (Java)]

1. I want to get the CFrame relative to the Motor6d by the offset. This is to create procedural animation frames from regular positions.

2. I am unable to get anything close.

3. I’ve looked over the dev forum and the API reference.

Is this what you are looking for, when you mean converting world space values like position relative to a Motor6D?

@dthecoolest

Using this knowledge, we have derived one very useful CFrame formula.

Here is what it looks like in function form and an example when applies to a common Motor6D rig like R6:

local motor = script.Parent
local target = workspace.Target

local function worldCFrameRotationToC0ObjectSpace(motor6DJoint,worldCFrame)
	local part1CF = motor6DJoint.Part1.CFrame
	local part0 = motor6DJoint.Part0
	local c1Store = motor6DJoint.C1
	local c0Store = motor6DJoint.C0
	local relativeToPart0 = part0.CFrame:inverse() * worldCFrame * c1Store
	
	local goalC0CFrame = relativeToPart0
		
	return goalC0CFrame
end

while true do
	task.wait()
	motor.C0 = worldCFrameRotationToC0ObjectSpace(motor, target.CFrame)
end

Wow it functions as if it’s just a regular part and you are simply setting the parts CFrame!

Thanks so much!
