Ok, I modeled a simple room with one window that I assigned this material to : DoubleGlazed_AlumFrame then I created a new material file (.rad) with the same name and I placed in Ectoect's library folder then I exported to radiance but I'm not able to get any renderings using this method , I get a blank picture in the image viewer within Desktop Radiance. I also tried Placing the new .rad file in the same directory as the ecotect file , still no luck.
any help .
I'm attaching a picture of the model in ecotect and two .rad files one for Laser cut panel LCP and the other for prismatic glazing.
I just discovered that I have this problem only when I choose low qaulity rendering , but it works great when I choose medium or high quality rendering
