Photometric Viewer

Bootcamp and a Windows Installation could be your friend.

Thanks - I shall take that under advisement as soon as I replace my five year old iMac with a new one.

Thea Render allows you to see the IES....

Exactly what the Photometric viewer on my link is supposed to do, were it to work on a Mac. I am a die-hard LightUp fan though, so will have to find something "stand alone" that I can use. Thank you.

LightUp loads IES files and displays their penumbra in the dialog

Indeed it does, but see how it is cut off at the end so you don't see the actual fall-off area? And I saw a demonstration of the other system and the ability to actually see what happens when you change the lumens in the viewer itself. I don't really know how to explain it, but it was very cool. I have no clue half the time what I am doing when lighting a scene (self-taught and not too successful in that area) and do it all by trial and error, so any pre-render visual is a huge help. In V4 of LightUp the new feature was the ability to be able to alter the lights position by hitting F5 and which would produce little axes manipulators by which the lights could be moved. Doing so on my Mac produces no such result however. The description of the various lights is all just goobledgook to me, so I really need the visual.
