3dsmax has had full raytrace support since version 2.0.
You might want to download the rayfx update from
http://www.blur.com/blurbeta as it has more powerful effects like better BSP division and area shadowing, as well as being more efficient.
MAX has radiosity (global illumination) support from various plugin renderers, the best of which are lightscape (standalone architectural type thing...VERY photoreal but a pain to setup and very slow), Brazil (still in beta, but kicking *** ), and Mental Ray (hugely expensive hi-performance all-in-wonder)
