i dont know exactly what is IES.....something with light values for spesific lamp types (?)

i dont know how painfull is to u Ono to Deploy this feature and if is worth the pain of this stuff,instead of confusing users....
if im wrong correct me!
thnx!

It's rendering correctly emitters as specific kinds of lightbulbs (you get saved from all the tons of work, modelling a realistic light source, and it also renders faster - so, it should be worth it)

as fas as I know IES files need a pointlight (spherical) model to be projected from... that doesn't mean that light will be sprayed in all directions, that's the subtle thing. Maybe by hacking a bit textured emitters on a sphere primitive... ?

With this implementation you can render the exact effect of let's say a halogen 30 lamp and it's wallwash effect on the wall at a given distance from the wall, and not only that, but will make indigo, not only a renderer but a tool for lighting design, which is one of my favourite architectural studies, and one hell of a scientific branch that has more technology that what you can imagine.

Ono already said, that he didn't take into account the size part, so, you should use a tiny (tinier) - [even tinier] mesh emitter

got it ppl!!!

The downside of using light definitions is that the luminaire (bulb) itself is not visible as a real bulb or even less as a neon: it's just a sphere :/

it's supposed to be combined with kind of a lamp shade, I guess...
