How can i solve this problem

Hello, first I apologize for my mistakes in English because I'm not an expert in that language.

I am encountering problems when rendering this, I am using sunlight and artificial light IES, the render this very time consuming and noises seem not leave, I would already help you to know what the best route to take

I already tried to use artificial lighting for material selfilumination but I also not had good results

anybody here?

can you post a screen grab of your corona settings? for interiors I always use hd cache secondary

you have very low rays/s (see http://corona-renderer.com/wiki/performance_debugging). Try to go through the checklist to see what causes it

i've made some changes following the tips above and i didn't got succes yet

what else should i do?

[Ondra]

well, you got 3times faster rendering, that is good ;)

You should probably not have light samples multiplier 20, that is too much. There is something wrong with the light emission, you probably have too many/too big lights in the scene. I would have to see the scene to be sure.

Maybe lights are intersecting with geometry?
