I am using desktop radiance in Ecotec. I am trying to analyse the glare effect produced by applying different screen transparency on a window. But when I applied the transparency in Ecotec to the screen material, (i.e. 12% ) the material disappear from my renderings. I know the material still there it is there since I can see the shadows it proyects on the floor. I enclose some of the images I got.
Figure 1 shows the deskto radiance rendering view from an exterior camera that faces the window of a room which has these exterior octagonal modules. The modules material that I chose is fabric with a transparency of 0% for this case.
Figure 2 shows the interior of the room and the shadows projected on the floor by the modules.
Figure 3 shows the same camera view as Figure 1. But in this case I changed the transparency material in Ecotec to be 60% and the modules are not visible anymore as it can be seen in. However when I render with desktop radiance an interior view similar to the one in Figure 2, it turns out that the modules are actually projecting shade, see Fig 4. It is quiet strange that the transparency material can be perceived on the projected shadows but it is not shown on the material itself.

I haven't seen your pictures but my guess is - without jumping to wrong conclusions -that your material, pressumably a 'trans' material, disapears from the images because its an illuminance image - the last reflection is missing. Try and run a luminance simulation and check if it becomes visible.
