Hello Guys,
I am trying to render some living room (still on progress)
any Comment and advice please
anyone know how to reduce firefly near desk lamp?

Hi Guys, just update some material, I dont know but its seem flat. any comment to improve it?

In some scenes using very small and very large light sources together results in noise in the illumination from the small light source. You can try increasing the size of the bulbs inside the desk lamps or decreasing the size of the lamps in the ceiling.

I see, Thanks Roeland

I like the render apart from the fireflies...!!

In this case, what I do is instead of reducing the size of the hidden fluorescent in the ceiling I "break" them in smaller pieces the size of the other lamps, that way they'll be similar in size and you'll see the fireflies "fly away"

@3rdeye : Thanks 3rdeye
@kubo : Hmm its a good idea. Thank you Kubo

Hi,

Light sources are sampled according to the area of the light sources. That is why in this scene, the small bulbs inside the desk lamps are not sampled often enough, giving the noise in the illumination coming from them. If you split a light source in pieces without changing the area, the noise will stay about the same. The only way to reduce the noise from the desk lamps I see is to either make the bulbs inside them bigger, or have less light emitting area in the ceiling.

You are right Roeland
I tried to break it but still many firefly

now I reduced the width of my plane light (uplight) and make the bulb larger, the firefly gone

OK, now this should be mentioned somewhere in documentation or sticky .. !! Or someone make a note of that for future reference - I was busting my head with that kind of problem also
