Indigo Renderer Forum

Hey, so im new to Skpindigo and ive been trying to render a few interior views. I often face a lot of difficulty with artificial lighting/ night views . The view rendered as night views take way too long and the fire flies/ white spots just keep getting worse is it goes. Im sure that this isnt meant to happen, which means that im not doing something correctly. what can i do to fix this? usually how long does a render take?

Wow, that definitely does not look right. The light sources should be low-poly and not too small. BiDir path tracing should be the best mode, if you're not using that already. Try a higher supersampling factor, like 3 or 4. Perhaps you could describe your light setup a bit more? A render at that resolution and at that rendering speed should not take more than half an hour to clear up.

Also, the brightness of white colour shouldn't be at 100%, 255 all the way. Something I read from a thread from a long time ago.

Yes, shouldn't go much higher than 200.

Avoid to put light sources behind glasses or - even worse - frosted glasses: try to keep the light sources as "clean" as possible (lowpoly and without blocking objects). For interior shots try BiDir MLT mode.

If you have both sun/sky and artificial illumination, put exit portals over the opening towards the oudoor spaces; if you only have artificial lighting set a black environment: this will help you (and us) to understand the behaviour of the emitters you put in the scene.

Which is your hardware configuration?

Thanks for the tips. I was doing an interior render and left it rendering all night only to wake up to a very noisy image. I tried the tips described by Pibuz and I cranked up an interior shot that rendered in 20 minutes what took the whole night on other settings.

Thanks!
