As you probably know, Lithonia is a lighting manufacturer. Here you can download, literally hundreds of FREE IES files for real-world lights. Just go to Resources > Photometric IES and download all of the photometric data files. Also check out this download:
This is an excellent IES previewer where you can render previews of IES files before you put them in your scene.
If you already have all of this, I’m sorry to waste your time, but if you don’t already have the Lithonia lights, you should get them. They truly are an excellent resource.
Do you work for them? :lol: Looks good anyway, ive been after some decent lights.
On another note ive seen someone use a program to make IES files before, with a rederable preview and fairly simple looking interface. Does anyone know what it was called?
I think pies.exe is another IES file viewer, the IES maker that was posted on this forum a while back is called ies_gen3.exe by some Russian guy called Kaba. I still have it if you want to try.
