WkLayerManager

"The very good script of David Humpherys - slightly modified. It creates a set of layers - exactly as in Photoshop - to classify objects of your scene. They are easy to select - hide or freeze. You can even use an alternate material for rendering! Fast and reliable - it makes big scenes simple to work on. Original script and versions for 3DS Max R3 and R4 can be found at REZN8. "
