Motor6d weld problem

Help and Feedback Scripting Support
#1

I am working on an fps engine for my game. I want to make the gun weld to the fps arms but this happens.

I assume I have to do something with CFrame:ToObjectSpace() but i am not sure because I’ve tried a few things with it.

When I create the weld I want to offset it by 1 stud in the direction of the players hands. But that offset is different with the camera direction or where the fps arms are facing.
Here is the code for welding,

EquipDebounce=true
local Model = Models.Client:Clone()
ContentProvider:PreloadAsync({Model})
local Conf = require(tool.Config)
local Handle = Model:WaitForChild("Handle")
local RightGrip = RightArm:WaitForChild("RightGrip")
-- Below I think is the problem. 
Handle.CFrame = (RightArm.CFrame-RightArm.CFrame.upVector*1)*CFrame.Angles(rad(-90),0,0) -- Offset
RightGrip.Part0 = RightArm
RightGrip.Part1 = Handle
RightGrip.C0 = RightArm.CFrame:Inverse()
RightGrip.C1 = Handle.CFrame:Inverse()
Model.Parent = Dummy

have you used c0 or c1 to offset the weld?

I forgot that existed. I will try that. I just did normal cframe here:

Handle.CFrame = (RightArm.CFrame-RightArm.CFrame.upVector*1)*CFrame.Angles(rad(-90),0,0)

Tried doing this but did something weird (Screenshot isn’t uploading)

RightGrip.C1 = Handle.CFrame:Inverse()*CFrame.new(0,1,0)*CFrame.Angles(rad(-90),0,0)

Would something like:

EquipDebounce=true
local AlreadyWelded = false
local Model = Models.Client:Clone()
ContentProvider:PreloadAsync({Model})
local Conf = require(tool.Config)
local Handle = Model:WaitForChild("Handle")
local RightGrip = RightArm:WaitForChild("RightGrip")
-- Below I think is the problem. 

if not AlreadyWelded then
Handle.CFrame = (RightArm.CFrame-RightArm.CFrame.upVector*1)*CFrame.Angles(rad(-90),0,0) -- Offset
AlreadyWelded = true
end

RightGrip.Part0 = RightArm
RightGrip.Part1 = Handle
RightGrip.C0 = RightArm.CFrame:Inverse()
RightGrip.C1 = Handle.CFrame:Inverse()
Model.Parent = Dummy

Would that work? let me know

At first glance no because I have a script that just deletes the weld when unequipped.
It would do the same thing because it uses this:

which is the problem

code for deleting weld:

Character.ChildRemoved:Connect(function(child)
	EquipDebounce=true
	if child:IsA("Tool") and child.Name==Equipped then
		Equipped=nil
		Dummy.Client:Destroy()
		ToolInfo.VPModel:Destroy()
		stopAllAnimations()
	end
	EquipDebounce=false
end)
