3D CGI Work - Caustics using Mental Ray in 3DS Max
Caustics are the lighting effects caused by focusing light through transparent objects. With the Mental Ray renderer that comes with 3DS Max it is possible to re-create caustics. In this example the caustics are caused by the moving surface on a cube of water.
