Holdable Camera Models Issue

  1. What do you want to achieve? Bottom left camera model at all times

  2. What is the issue? When I crouch (changes the humanoid hip height), held items don’t correctly teleport to the camera’s CFrame

  3. What solutions have you tried so far? Tried teleporting to humanoidRootPart instead of camera, using PreRender, and using Position rather than orientation

function render.render()
	local mouseDelta = UIS:GetMouseDelta()/50
	local swayX = math.clamp(mouseDelta.X, -0.2,0.2)
	local swayY = math.clamp(mouseDelta.Y, -0.2,0.2)

	swayCF = swayCF:Lerp(CFrame.new(swayX, swayY, 0), .2)

	for _, v in cam:GetDescendants() do
		if v:IsA("Model") then
			local camCFrame = cam.CFrame
			v:SetPrimaryPartCFrame(camCFrame * swayCF)
		end
	end
end

Since this is a module and can’t run RunService I have them in a local script that calls the module.

RunService.PreRender:Connect(function()
	RenderViewport.render()	
end)

Below is an image of how I have it setup

Try applying an offset cframe (before applying the sway cframe) when you are crouching. Just make crouching an attribute perhaps so it’s easier to detect.

That solved the issue; however, I am presented with another problem. When looking up, down, etc., the tool gets further away from the camera view while crouching. Here is the updated version:

local swayCF = CFrame.new()
local crouchOffsetCF = CFrame.new()

function render.render()
	local mouseDelta = UIS:GetMouseDelta()/50
	local swayX = math.clamp(mouseDelta.X, -0.2, 0.2)
	local swayY = math.clamp(mouseDelta.Y, -0.2, 0.2)

	swayCF = swayCF:Lerp(CFrame.new(swayX, swayY, 0), 0.2)

	local targetCrouchOffset = char.PlayerValues.inCrouch.Value and CFrame.new(0, -1, 0) or CFrame.new(0, 0, 0)
	crouchOffsetCF = crouchOffsetCF:Lerp(targetCrouchOffset, 0.2)

	local finalCameraCFrame = cam.CFrame * crouchOffsetCF * swayCF

	for _, v in cam:GetDescendants() do
		if v:IsA("Model") and v.PrimaryPart then
			v:SetPrimaryPartCFrame(finalCameraCFrame)
		end
	end
end
