Delete Empty Layers

fn delete_empty_layers =
(
	local counter = 0
	
	for id = LayerManager.count - 1 to 1 by -1 do
	(
		local layer = LayerManager.getLayer id
		
		local contains_nodes = LayerManager.doesLayerHierarchyContainNodes layer.name
		
		if not contains_nodes then
		(
			local deleted = LayerManager.deleteLayerByName layer.name
			
			if deleted then counter += 1
		)
	)
	
	return counter
)

Thanks. This is more clever way for latest version of 3ds max and its "new" layer manager.

that worked beautifully!
