Emitter through AGS or half sphere emitter?

Which will clean faster in V2?
I have some downlights which are spheres and naturally they are about 80 polygons each at least. Is that too many polygons to assign an emitter material to or should I just enclose single planes inside an AGS half cylinder?

I could make a guess, but it would be so much better to see you do some quick tests and post your results.

Why do you want to enclose a plane inside an AGS half cylinder?

He said half sphere. :wink: I think he want the dome to be illuminated and be a source of light in the scene, right?

No, he said cylinder :D

But anyway, don't enclose emitters and waste time. Why not making the cylinder or hemisphere themselves emitters instead...

Yes I said cylinder but I meant half sphere.
Bubaloo was correct. I want to use those half sphere domes as downlights
I am skeptical about assigning an emitter directly on the spheres because the manual says that multipolygonal emitters reduce performance.
The domes are currently 80 polygons each
thanx for the prompt responses :D

Then, it has forgot to say not to hide emitter behind other stuff, because it's far more harmful than using a high poly emitter alone :mrgreen:
Also, 80 poly doesn't sound that bad... Give it a try ;)

Thanx
I'll post results soon. V2 is coooool.
