thank you... I think I've fallen in love with Indigo

you are so right!
now with MLT and some changes for material

Here is my next try to set up the night scene. Can't get rid of the fireflies, though it rendered about 22h and has 8500spp, supersample set to 3. Render method Bidir Path Tracing.

I have a GeForce GTX 285 with 1024MB RAM.
The tree and the pebbles are external obj meshes.

Hi Zoom-B,

thank you for your kind words

I will try to follow your advices. But regarding gpu acceleration, I get an error when I activate it, see attached. What happens here?

Ok, bidir with MLT started and I get 7k/s! this is so damn slow... after 30min 11spp. This will need days to get free of noise! All I want to achieve is a nightscene with some warm light inside the building. Perhaps the material of then windows panes is the wrong one? I used the normal glass for the...

Ok, next try is bidir with MLT. Seems I've chosen quite a complicated scene for my first steps with indigo.

Here is my try for the nightscene after 11h of rendering, about 8000spp.
-path tracing
-glass acceleration

looks quite bad with all these fireflies...

Thank you Pibuz and Headroom for your explanations :) I remodeled the lamps and changed materials, now it seems to work much better. But I'm still trying to get some lights coming out of the building. Whenever I use bidir the inner building through the window stays black, though I tried different ma...

thickness of glass is 5mm. I will try a different material for the glass.
thank you!

Do you mean by "transmitter" the glass surrounding the bulb (which uses a diffuse material)? Or the emitter itself?

attached is a picture of the lamp. Inside bulb with emitter (cylinder), outside cylinder with glass material.

ok...I'll try.

bidir doesn't seem to work, it gives somehow a week diffuse light from the emitters... see attached

and patch tracing creates a lot of fireflies...

well, I'm not able to set up a natural looking sky at night. It always looks orange or is far to bright for a night scene. I figured out that using the sketchup background set to a dull dark grey/blue seems to fit best, but I'm wondering how to use the physical sky that is mentioned in all tutorials...

The pepples came as obj, and I used them as external meshes in sketchup, like the tree. But I have one more question. After watching the tutorials about emitters and environment, I tried to set up my scene at night, by using emitters in the lamps outside the building.... and totally failed :cry: I w...
