Hi, i am working with radiance and very interested in simulating diffuse transmitance materials in radiance. OS 1.7 is supposed to be able to model material either 100% specular or 100% diffusing.

I have downloaded and installed 1.7 but when i perform a radiance simulation i am getting the following: INFO: simulation command generated no results, stuffing with 0's

and then the illuminance maps are full of 0s.

Is this a bug or i am doing something wrong ?

If i install 1.6 or 1.6.1 and do the same simulation, i can obtain results different from 0s.
