You can probably use CurrentCamera.ViewportPointToRay(), then face the part pointing toward the Ray.Origin or something.

Okay here’s the file, there’s a single LocalScript in StarterPlayerScripts (it has to be local cuz each player has their own camera).

I don’t know if there’s a better way, but this is what I thought of (maybe someone else will reply with a better way)

Basically every frame (render stepped) I create a ray from the camera with CurrentCamera.ViewportPointToRay(), then I just position the cframe of the part facing that ray.Origin using CFrame.lookAt.

I should warn this is going to move it relative to the center of the part (because that’s the CFrame), if you wanted it to it to have offset or something that would be more work.

I’m guessing in order to make the grass effect it’ll need more work

No problem, you might need to edit it so it works in your situation, especially if you have a lot of grass parts.

Let me know if you need anything else

Yes you would have to use a for loop.

You would do it something like this:

local RS = game:GetService("RunService")

local cam = workspace.CurrentCamera
local part = workspace:WaitForChild("put-ur-part-here") -- replace the text in brackets to the name of your part

local camX = cam.CFrame.Position.X
local camZ = cam.CFrame.Position.Z


RS.RenderStepped:Connect(function()
	part.CFrame = CFrame.lookAt(part.Position, Vector3.new(cam.CFrame.Position.X, 0, cam.CFrame.Position.Z))
end)
