IES Generator Tool for Custom Profiles

Hello all!

i`ve found this tool and it is quite fun to use and create your own IES profiles (windows only). Enjoy

Thanks for sharing!

It could be cool if that were a tool integrated into a standard spot light. That way, even if you don’t have an IES light specific for a scene you can create some really nice lighting effects.

You could also try this one - it’s more versatile and has some technical graphs for lighting as well

Is there such thing as a parametric IES file? I’m working in Revit and want to create a family for a linear light fixture with an IES that can adapt to the length the user inputs.

Edit: I have seen both opinions.

  1. Use Emissive materials.

  2. Use IES files.

Should I even be looking at IES? Emissive works for quick things and looks good, but I can never “throw” light in any predictable manner.
