Hi,

I have problems with the Octane lights and render time for animation.
When there is only a sun we have good result with only 2000 or 3000 samples, but if we add some light, Black Boddy or texture emition we need more than 16000 sample to have an acceptable result.
Wy the lights don't work like the sun? Did somebody have a solution? I don't find anything on the documentation.

Up to a point, that is one of the characteristics of Octane. Lights render faster when the emitting surface is larger and you can adjust the sample rates of the light sources. Try turning the rate on your light up to 1000/max. Other than that, there are of course a number of things you can do to optimize a scene. Coherent ratio can help a lot with scenes full of lights.
