Hi there
maybe someone can help me, but I have been trying to get the IES intensity scale inside the blueprint for a light fixture
temperature setting works, IES file changing works but this IES Intensity scale seems to play tricks on me. All is set to use IES and not the regular intensity
found a node for Set IESBrightnessscale but cant seem to make it work
Unfortunately the IES intensity scale is not exposed to blueprints. You could however still adjust the lights main intensity and also use set visibility with blueprints.
Sorry for the late response John but never got it to work, as like Steve says it is not exposed, using the intensity works of course but is not correct from an official lighting point of view.
