[Need Help] R6 Neck don't do rotate a head, but rotate the torso instead

[Wheatley_XD (Co0lestUncle)]

1. What do i want? :
   I want rigtype R6 head movement feature that following the Vertical direction of camera BUT within my custom first person camera(my cameratype is Scriptable, so i have scripting all behavior by myself) that locking the head too, So my HumanoidRootPart have to rotate in Horizontal direction of camera.

2. So what is the issue/problem i encountering? :
   To rotate the head, Using the motor6d call “Neck”, right? But instead of rotating the Head Vertically, It just rotate the Torso Vertically that it should to just only rotate itself in Horizontal.
   

I was finding a cause of this issue by disable some of feature to test them if without it, Another one would work and this is result:
i was disable humanoidrootpart’s rotation

– Disabled : Hrp.CFrame = CFrame.new(Hrp.Position)*CFrame.fromOrientation(0,CameraRotation.X,0)

neck.C0 = CFrame.new(0,yOffset,0)*CFrame.Angles(math.asin(CameraLookDirection.Y) - math.rad(90),ry,rz)

head follow the camera feature was work normally.

another while i disable head follow the camera feature

Hrp.CFrame = CFrame.new(Hrp.Position)*CFrame.fromOrientation(0,CameraRotation.X,0)

– Disable : neck.C0 = CFrame.new(0,yOffset,0)*CFrame.Angles(math.asin(CameraLookDirection.Y) - math.rad(90),ry,rz)

humanoidrootpart rotate in Yaxis (Horizontal) ,So it was work normally too.

3. What solutions have i tried so far? “Did you look for solutions on the Developer Hub?”

• I tried move the neck’s parent into the head, and it doen’t solve anything
• I tried use CFrame of neck’s Part1 (neck.C1) and of course it doesn’t solve

Body rotating with neck slightly

You can write your topic however you want, but you need to answer these questions: What do you want to achieve? Keep it simple and clear! I need the neck to turn but its not working What is the issue? Include screenshots / videos if possible! (sorry for the long video the pausing didn’t work) What solutions have you tried so far? Did you look for solutions on the Developer Hub? tried to get some solutions on yt and dev forum but they dont work and when i try to do it m…

i was found this forum, he has simillar problem but it still don’t have anything that be solution for my problem i encountering.

For make you easier to hep me. here the code i wrote.

			local CameraLookDirection = Camera.CFrame.LookVector
			
			local _,ry,rz = neck.C0:ToEulerAnglesXYZ()
			neck.C0 = CFrame.new(0,yOffset,0)*CFrame.Angles(math.asin(CameraLookDirection.Y) - math.rad(90),ry,rz) -- most of neccesary part of this topic
			
			local hrpY, hrpX, hrpZ = Hrp.CFrame:ToOrientation()
			local raw = Head.CFrame * CFrame.Angles(-hrpY,-hrpX,-hrpZ)
			local rot = CFrame.Angles(0,CameraRotation.X,0) * CFrame.Angles(CameraRotation.Y,0,0)
			
			Camera.CFrame = raw * rot * CFrame.new(0,0,5)
			Hrp.CFrame = CFrame.new(Hrp.Position)*CFrame.fromOrientation(0,CameraRotation.X,0) -- most of neccesary part of this topic
		end) 
end

Note: I wrote this script it in Module Script, So i tired my best to get neccessary code for showing

You can ask anything, If you confused anything about this topic but please help and try your best, Thank you.
