Oh never mind, all you have to do is group all the parts you want to filter and use to make a model and using mouse.targetfilter on the model should work.
You can use TargetFilter to filter objects from the mouse. Just say:
local Mouse = game.Players.LocalPlayer:GetMouse()
local folderToFilter = workspace:WaitForChild("FolderToFilter")
Mouse.TargetFilter = folderToFilter
The mouse will not detect any objects if they are in the folder. You can also use a model for this if you prefer as it doesn’t matter as long as every object you want to filter/ignore is in that model/folder. This is actually exactly what I do with my placement module v3. I filter the folder where all the models are stored on the players plot so it’s easy to place down objects. Hope this helps!
