Turret Machine Gun Angle Lookvector Thing problem

Help and Feedback Scripting Support
#1

  1. I want that my Turret LeftRight Motor6D rotates correctly according to the Rotation of the Camera

  2. When the Turret Base gets rotated, the angle is not correct

  3. I have tried many different approaches, like rotating the cameraCF with the Y Rot. of the Base Part

You can see things i tried allready as comments, i am new to all these angle calculation things and advanced CFrame stuff.

This is only a code Snippet:

if cameraCF and seat.Occupant then	
			--[[
			local angle = -Vector3.xAxis:Angle(mouseCF.Position)
			local _,_,currentUpDownAngle = Motors.UpDown.C0:ToEulerAnglesXYZ()
			local _,currentLeftRightAngle,_ = Motors.LeftRight.C0:ToEulerAnglesXYZ()

			if currentLeftRightAngle < maxLeftRightAngle and  currentLeftRightAngle > -maxLeftRightAngle then
				if angle <= currentLeftRightAngle then
					Motors.LeftRight.C0 = Motors.LeftRight.C0 * CFrame.Angles(0, radSpeed  , 0)
				elseif angle >= currentLeftRightAngle then
					Motors.LeftRight.C0 = Motors.LeftRight.C0 * CFrame.Angles(0, -radSpeed  , 0)
				end	
			end
			--]]
			
			--local axis = Vector3.xAxis.Unit
			local primPartCF = script.Parent.PrimaryPart.CFrame
			local lookVector = (cameraCF ).LookVector --* (primPartCF.RightVector + (primPartCF.LookVector) * Vector3.new(1,0,1))
			local upDownLookvector = -(cameraCF * CFrame.Angles(math.rad(10), 0,0) ).LookVector  * Vector3.new(1,1,0)
			
			--local angle = math.acos(lookVector:Dot(axis))
			--if lookVector.Z < 0 then
			--	angle = -angle
			--end
			local _,baseRot,_ = primPartCF:ToEulerAnglesXYZ()
			--local angle = math.clamp(math.atan2(lookVector.Z, lookVector.X), -maxLeftRightAngle - baseRot , maxLeftRightAngle + baseRot ) 
			local angle = math.atan2(lookVector.Z, lookVector.X)
			--calculate position between z and x 
			
			local upDownAngle = math.clamp( math.sin( upDownLookvector.Y ), maxDownAngle, maxUpAngle)
			
			local moveThreshold = 0.01
			local _,currentLeftRightAngle,_ = Motors.LeftRight.C0:ToEulerAnglesXYZ()
			local _,_,currentUpDownAngle = Motors.UpDown.C0:ToEulerAnglesXYZ()

			if math.abs(currentLeftRightAngle - angle) >= moveThreshold then
				Motors.LeftRight.C0 = CFrame.new(Vector3.new(0,-0.5,0)) * CFrame.Angles(0,angle,0)
			end	
			
			if math.abs(currentUpDownAngle - upDownAngle) >= moveThreshold then
				Motors.UpDown.C0 = CFrame.new(Vector3.new(0,-0.75,0)) * CFrame.Angles(0,0,upDownAngle)
			end
