Raycast filter not working correctly

[Iricai_Games]

I am making a building system and the model preview should not be considered on the raycast. However, that is not happening for some reason. Here’s the code that matters:

local function visualizePreview()
	if CLIENT_CAST and CLIENT_PLOT_PREVIEW then
		if table.find(ClientPreviewFolder:GetChildren(), CLIENT_PLOT_PREVIEW) then
			CLIENT_PLOT_PREVIEW:PivotTo(CFrame.new(CLIENT_CAST.Position) * newOriention)
		else
			for i, instance in ClientPreviewFolder:GetChildren() do
				instance:Destroy()
			end
			CLIENT_PLOT_PREVIEW.Parent = ClientPreviewFolder
		end
	end
end

local function updateMouseCast()
	local mouseLocation = UIS:GetMouseLocation()
	local unitRay = camera:ViewportPointToRay(mouseLocation.X, mouseLocation.Y)
	local params = RaycastParams.new()
	params.FilterType = Enum.RaycastFilterType.Exclude
	params.FilterDescendantsInstances = {player.Character, CLIENT_PLOT_PREVIEW}
	CLIENT_CAST = workspace:Raycast(unitRay.Origin, unitRay.Direction * MAX_DIST)
	print("updated cast: ",CLIENT_CAST)
end

local function onMouseMove()
	updateMouseCast()
	visualizePreview()
end

edit: btw i am running these functions, not just declaring them

That’s happening because you’re not passing down your “params” to your raycast.

Here’s a corrected version;
CLIENT_CAST = workspace:Raycast(unitRay.Origin, unitRay.Direction * MAX_DIST, params)
