[Radiance-general] rtrace vs. rview, mirror vs. metal or BRTD

[Germain Augsburger]

Hi, I wish you a happy New Year! Starting with a radiance-issue...lol

In my Radiance scene I replaced my "mirror" materials with "metal" (or even "BRTD"), and although rview obviously "sees" the new material, rtrace doesn't "see" anything (irradiance measurement -I). I tried to set the rview and rtrace options as similar as possible (for instance -dr, -aa, -ar, -ad, -as) but so far without success. Is there a way of getting "metal" or "BRTD" work in a similar way to "mirror" with rtrace?

My 3 scenes (field of mirrors reflecting the sun towards a central receiver, 3 times: with "mirror", "metal", and "BRTD") are available if needed (too big in a general radiance mail); and here are some of my command lines (first "cd HelFiSim"):
