Hi,

I didn´t really understand your answer.
On the left side I have two retangular emissive polys on the ceiling + six round polys at the spot lights (8 polygons total).
On the right side I have two Octane lights on the ceiling + six Octane lights set to the spot lights (8 Octane lights).

So the "light"-amount is the same at both images. Shouldn´t the lights create similar results if the Octane lights are just polys that have emission nodes attached to them?

Yes, but your left scene has all the polygons in the same Octane object node, and the round polygons are triangulated at render time, so you have more triangles than using the Octane lights.

The right scene, using the Octane lights, has simple quad polygons, and each polygon is inside an Octane object node. I am not sure, but perhaps if you have several objects with only one quad polygon inside, Octane works better than if you have only one object with all the polygons inside it.

Anyway if you want to send to me the test scenes I could test them here. Perhaps the polygons in the left scene are not exactly in the same place as the Octane lights, so the left scene could have more noise due to specular reflections from the emission polygons placement ... it is hard to say.

Thanks,

The triangulation was a good point. Didn´t think of that.
I will test if I use just quad polys in the spot lights and see if there is a difference.

Was this been resolved ? Any conclusion/result to share with rest of us ?

Thanks

Ditto! I'd like to know the conclusion as well.
