why this file render to black after i added a cube into it?
weird, at first, i downloaded the file from 3d tutorial site, i rendered it, and i got a nice output like below.
so, i wanna see what if i added a new cube into it and use a phong (material? or call shader??) like the cynlinder.
but then, i got a total black output?? why? any idea?
btw, you can download the .mb file from here.
