Hi all,
I’m trying to use UE5 for physically accurate lighting purposes and I want export an EXR image of luminance values or anything that can be tied to a physical unit (e.g. lux or lumens). How can I do that?
Thanks,
Brad

You can setup lights in the scene using Lux or Lumens. When using the screenshot tool you can export using EXR, it is a property you can check.
