Viewmodel Positioning below the World?

Help and Feedback Scripting Support
1

So when trying to recreate a viewmodel, I got to the Part where i need to Position it with the Camera, but when i did so, it positions it below the World?

I Checked, The Model is inside the Camera:

Why is this the case, I’m using this code:

LocalScript:

local CSvc = require(game.ReplicatedStorage.Modules.ClientService)
-- CSvc Stands for ClientService (as you can see)

local VM = CSvc:newVModel()

CSvc.PreRender:Connect(function() -- RunService.RenderStepped
VM:SetPrimaryPartCFrame(CSvc.Cam.CFrame) -- CSvc.Cam = workspace.CurrentCamera
end)

ModuleScript:

local C = {}

C.Run = game:GetService("RunService")

C.PreRender = C.Run.RenderStepped


C.Plr = game.Players.LocalPlayer
C.Chr = C.Plr.Character or C.Plr.CharacterAdded:Wait()

C.Cam = workspace.CurrentCamera
C.VModel = game.ReplicatedStorage.Viewmodel


C.VCFrame = CFrame.new( 0 , -1.5 , 0 ) -- Viewmodel Offset (Not Used)

function C:newVModel() -- clones a Viewmodel
	local Clone = C.VModel:Clone()
	Clone.Parent = C.Cam
	
	return Clone
end

return C

I Went through Proccess and elimation to find my issue, and I have no idea what my issue is, the Viewmodel is welded with Motor6Ds, I Double Checked my Code to see if I was doing anything wrong, nothing, Why is this happening? Am I missing something?

the only solutions I can think of is

Make sure at least one part is anchored (preferably the primepart)

Just for the sake of it try just using workspace.CurrentCamera.CFrame to see if the table is the problem

Try to parent the vm to world model to see if it has anything to do with roblox physics

other than that I can just wish you good luck

3

Yes, I tried but it makes the Model fly un controllably

Doesnt work either

That breaks the Viewmodel

I tested with an unanchored Part, works fine
I tested with basic code works fine with the Part

Its just the Viewmodel that isnt working

4

Can you show a ss of the vm and its descendants?

I don’t get why it isn’t working. The only thing I’m thinking is if the renderstepped loop is even running. But other then that I don’t know. But I gotta go now, I’ll check tomorrow when I have access to a computer if you haven’t solved it

7

Maybe try printing the cframe coordinates every renderstepped.

Yeah, Im not sure about that:

God I am such an idiot, I used Camera instead of CurrentCamera

After that my Issue was fixed

RobloxScreenShot20230111_201958115

11

Welp, Having the Issue again

12

Hello.

I highly recommend you to not use the Model::SetPrimaryPartCFrame method and, instead, make the use of Model::PivotTo method. If you do not want to use the latter, you can try the method below which is guaranteed to work.

local function moveModel(model, cframe)
    local main = model.PrimaryPart
    local mainCFrame = main.CFrame
    for _, part in next, model:GetDescendants() do
        if part:IsA("BasePart") and part ~= main then
            local offset = mainCFrame:ToObjectSpace(part.CFrame)
            part.CFrame = cframe*offset
        end
    end
    main.CFrame = cframe
end

Best regards,
Octonions

Does the same thing as PivotTo but without the PrimaryPart

Explain?

14

Model::SetPrimaryPartCFrame throws off errors if you execute it many times. The offsets of the model begin to shift randomly around because of numerical approximation.

moveModel will take your model and it’s PrimaryPart, and then it will apply a linear transformation in order to preserve the offsets of your model. It tends to minimize the approximation because of the raw cframe values.

15

Not Exactly

Using RenderStepped would throw errors if so

Has never happened with me

16

I wonder why you are asking for help then.

17

because, the viewmodel is for some reason positioning itself blow the world when im setting to the Camera’s CFrame, i got it working until it suddenly broke again

@Octonions neither PivotTo, SetPrimaryPartCFrame, or your code work, it continues to position below the world


(Viewmodel gets destroyed at the end)

18

@Octonions @AMisspelledUsernaem @screenswitch1
Ok, so after a bit, it appears that its some weird Sizing Issue, for some reason, it appears to be below the Map, while its Parented and Position to the Camera, Which I find quite odd. Why would this happen?

There is only 2 Parts, and for some reason its being positioned below the map?

Would this cause issues?
How would I Fix it?

19

I do not know. You seem to have the answers to solve your problem already.
