I have this exact scenario. I am loading a simple sphere with blue plastic
material on it with simple ambient lighting. I am also using the Starfire
driver and my log file includes similar output as below and appears to be
error free, but I just get black space, no object. I created the file in
3DS3, not MAX, but the old version 3 that runs in dos or a dos window. I
saved the file as 3DS format. Has the format changed in the latest 3DS
versions? Should the Starfire driver work with this old version of
3DStudio?
thanks,
daveh
