speeding up render.. (lumi polys?)

[_mats_]

Hello -

I want to thank everyone in advance for the help I always had in this forum, as usual I have some more questions..

I am wondering how can I speed up my render, right now the main issue is that long luminous poly that illuminates the backsplash, under the cabinets, its a 300% luminosity, 0% diffuse material.

I upped the luminous samples to min 600 max 1200 (less than that was beginning to come out noisy).

Is there any other way to speed it up, any setting I can tweak?

Thanks !

PS : forgot to mention that I tried an area light and a linear light instead of the lumi poly but it still takes too long to render.

Thanks !

If the luminous poly is "only" 300% luminous i suggest you render it in luminosity model/indirect. It will be way faster and you might need to up the finalgather rays to get a splotchfree image but overall it will be much faster.

Thanks Silver

I am trying that right now

PS : wow, MUCH faster, from 1hr to 1min 20 secs.

Guess what setting I will be using from now on??

Thanks Silver !

Yes indirect mode is much better for this kind of light because it will render light nice and smooth. It will not cast very detailed shadow though but this is not important since light is quite big compared to small items it might illuminate.

Is that also true for the skylight procedural from Denis when rendering outdoor scenes?

No, this only applies to surfaces (polygons) with luminosity.

OK, thanks.
