Issue with Motor6D Orientation

[SebasDMi (Sebas_4501)]

Hi, I’m encountering an issue when trying to connect two parts using a Motor6D. In my code, I set C1 to have a specific orientation (90, -90, 0). However, when running the game, the properties of the Motor6D display a different orientation.

Below is the relevant code block:

UserInputService.InputBegan:Connect(function(input, gameProcessed)
	if gameProcessed then
		return
	end

	if input.KeyCode == Enum.KeyCode.F then
		if not CurrentItemSelected then return end
		local ItemModule = GunsModule[CurrentItemSelected.Name]
		
		local PATH_MODEL:Model = ItemModule.PATH_MODEL:Clone() -- This is a model
		PATH_MODEL.Parent = ViewModel
		local Part0 = ViewModel:FindFirstChild("Right Arm")
		local HandleMotor6D = Instance.new("Motor6D")
		HandleMotor6D.Parent = Part0
		HandleMotor6D.Name = "Handle"
		HandleMotor6D.Part0 = Part0
		HandleMotor6D.Part1 = PATH_MODEL.PrimaryPart.Handle
		HandleMotor6D.C0 = CFrame.new(Part0:FindFirstChild("AttachArm").Position)
		HandleMotor6D.C1 = CFrame.Angles(math.rad(90), math.rad(-90), math.rad(0))

		CurrentItemSelected:Destroy()
		CurrentItemSelected = nil
	end
end)

When running the game, these are the properties generated for the Motor6D. The issue lies in the orientation of the C1 attribute:

Key Details:

1. Purpose of the Code: This script creates a Motor6D to connect a cloned model (PATH_MODEL) to the ViewModel.
2. C1 Configuration: I’m using CFrame.Angles with values (90, -90, 0) to set the desired orientation.
3. Unexpected Behavior: Despite configuring C1, the orientation shown in the game is different from what I set.

Questions and Context:

• Am I setting C1 incorrectly?
• Could the relative position between Part0 and Part1 be altering the orientation?
• Is there any additional transformation required to make C1 work as intended?

I’d appreciate any guidance or solutions to this issue. Please let me know if you need more details.

Whenever you’re doing Motor6D orientation, you should get the old position of C1. and then multiply with the CFrame.Angle Orientation.

Example Code:

local Motor6DOrigin  = Motor6D.C1

Motor6D.C1 = Motor6DOrigin * CFrame.Angles(0, 0, 0)

I hope this was helpful!

I already tried as you said and it didn’t work, it’s still the same.

When it is running, if you manually set it to what you wanted does it work?

Of course, when doing it manually, the orientation is correctly placed in the game.

Oh wait it is correct. That’s orientation which is different to what CFrame.Angles does

You might want to use CFrame.fromOrientation(math.rad(90), math.rad(-90), math.rad(0))
