Path tracing need emitting light to shoot photons (afaik). So when you select "solid color" as background there's no sunsky, thus no light to emit. Same occurs outdoor too.

Thank you!
I understand it(outdoor scences are only tests)
I trying to render indoor scences like - http://rapidshare.com/files/45915944/sb1_sf.rar.html
I also try to "play" with different settings of gi-types
For example, i use "standard" ui-setting:

1. render-sett.: res.- 800x600; gi - high; aa- none
2. background sett.: bg type - sky
   and when i render and start-up message about "photon mapping enabled, but no globals photons to emit". it's for light-object
   Ilay

P.S. maybe some technical questions are asked on official forum?

[Didier Bur]

I suppose that when one is indoor and the sunsky is not visible (no openings to the outside) and when there is no light inside the room, SF considers that there are no photons to emit ?
I'm not familiar enough yet with SF to be sure of that. Maybe you could ask Eugene or fpsunflower at the official forum.
Cheers,

Ok! I ask.
I try to illuminate by one light - "sky+sun" - sky-object(for daylighting)

Ohhh, Didier! What are you think about simulated(artificial) lighting?
maybe it' like materials, only to group = sf-"light.name_group".

Sorry for my bad English, my russian is native.

[Didier Bur]

Artificial lighting will be supported in next release (point light, spot, and so on).

I test AO-settings

Hi all,
When coding the SketchUp2SF plugin, I started to experiment shaders.
These first experiments can be downloaded as a library here:
http://www.crai.archi.fr/RubyLibraryDepot/Ruby/Sunflow/thumb.html

Or go to my site and click on the Sunflow Shaders menu.
Enjoy,

Didier, it's great! Thank you
Do you work at material editor or something?

[Didier Bur]

No,
I'm just trying to get good parameters mainly for diffuse and glass shaders to implement the SU materials convertion in the plugin.
Cheers,

P.S.: Be back 08.25 (holidays )

[ilay7k]

Have a nice holidays. I glad for you, I will be working from 02.08

It's handly, writing into .sc? Or ...
