Lumi noise

[darickster]

Hello people,
I'm posting this, the job is done the client was happy but i wasnt. What bugs me is the noise the lumi's are causing. I upped the photons through the roof but it just comes out horrible.

To improve what is the best way to handle a situation like this?

Any help is welcome.

Is lumi calculated as direct or indirect? can you show wireframe of your ceiling?

[jure]

Oh and very nice work!

Hello Jure,
The lumi are calculated indirect in render settings.

Surface luminousity is 500000
krayshader lum number 500
compute as indirect in shader is off

geometry is one large poly which is the ceiling and chroom ring with lumi poly inside only, no glass on top.

[jure]

please show wireframe if you can.

posting these wires, one is scene in layout, other is model closeup ceiling.

hmm strange, i don't see anything in those wireframes that woul cause the noise. Perhaps you could isolate part of the scene and send it to me to investigate?

To me it lloks like trees reflected on the glass

no, i am referring to the white grain around the spots as seen in detail.jpg
