Maxscripts These are lines of code that can be used to creat custom tools in 3ds max. Examples are Camera Switcher (allowing the switching of cameras at render time, therefore eliminating the need to batch render) Clay Render (applies a clay material to the objects in the scene, renders out the image and then undoes it all. Great for checking out lighting and shadows. It does not affect any materials already applied.
Remember... the early bird might get the worm, but the second mouse always gets the cheese!
