Rhino 7 brought welcome updates on lighting including falloff and Inverse Squared. It's not still IES, but should be good enough for most cases.
However, Enscape doesn't seem to behave correctly with updated lighting. I tried all different units, MM, M, IN, FT, but I don't see any change in behavior. It's really hard to fine tune the light intensity in the regular 'constant' mode. What's more problematic is, 'Inverse Squared' is like just light turned on/off. It's also supposed to work more realistically with distance between light and objects, but 'Inverse Squared' light becomes way too bright even at .1.
Is there something I'm missing to use the updated lighting correctly with Enscape?
