hi^^ abicalho
Thank you for reply..first of all, there is only one light(free area)in my scene. Second of all, of course I used "render direct illumination".
for the test, I made 1 box for room and 2 red sphere(one is excluded from radiosity calculation) and calculated the radiosity. and then rendered the scene. 1 red sphere's black(exclude one)and others(box,another sphere) are fine. hooo~~~OK here's the reference.

See the third paragraph in "Suggestions for Saving Time". She said ".... they won't change the rendered image much (see Figure 1)." but they will.. very much...BLACK!! she's wrong? I don't think so. I don't know what's the problem. Anyway thanks you
