How would I go about excluding parts in a folder without excluding the models within the parts?

I wish to exclude the parts in a folder named Spawn1 up until Spawn6, but not the models within the 6 parts… How would I change the parameters within my script to reflect such? Any help would be most appreciated. Below is the parameters I already have, and screenshots of the hierarchy of parts.

local params = RaycastParams.new()
params.FilterType = Enum.RaycastFilterType.Exclude
params.FilterDescendantsInstances = {workspace:FindFirstChildOfClass("Terrain")}

Disable CanQuery on the parts (you need to also disable CanCollide on the parts for the option to show up)
