skylight bug?

[dagobert]

I use blender 2.45, blendigo 0.9 and indigo_v09_test6. And when i render with sun light set up i got a black back ground. did i forget to do something?

Do you have any meshlights in your scene?
What type of tonemapping do you use?

[dagobert]

I got no mesh light in the scene. And nothing in tone map except Reinhard
my idea was that if you use physical sky and sun. it will create a sky according to the sun.
like in http://www.indigorenderer.com/blender_tut/#6a in the outdoor scene exemple. the background don t seem to be a picture in the background

[Kram1032]

you used physical sky + sun?
Ok.
Did you change the default spot to be a sun-light?

[dagobert]

my scene got no light by defaut. i set it like that. So i had a sun light in the scene. did someone got a scene to download,
where you got a sky background

[Kram1032]

can you make a screenshot of both blendigo with the environment tab and your sunlamp?
Should work without problems, usually...

[dagobert]

if you got a scene with a cube that works i will be happy to test it.

[Kram1032]

do you use the yafRay-rendersettings? O.o
Make sure, you're on Blender Internal!

Oh, and the extra-atmospheric is very very very very very slow!
You'll want to deactivate BiDir, if you use it. And even then, it'll take, like, forever.

[dagobert]

i heve done everything but still don t work. i you got a scene that work for you i d like to test it here.
I m using xp.64...

[dagobert]

it s the extra atmosperique that don not work as i was thinking. it remove the sky and do an awfull rendering. don t know why?!

[Kram1032]

It doesn't remove the sky, but as I said, it takes for ever!

Oh, and the extra-atmospheric is very very very very very slow!

what the hell is extra atmospheric ??? ? ??

[fishbowl]

for the record,
"extra atmospheric" means out of the atmosphere. When it's turned on, attenuation and scattering in the atmosphere is turned off; the incident sun radiation is equivalent to that at the outer edge of the Earth's atmosphere.

It's basically for rendering in a vacuum. Indigo. In. Spaaaace!

I believe, you can use a specular material with an "atmospheric" medium to simulate an enclosed atmosphere, I haven't tested it, but it looks like SmartDen did.

Extra atmospheric is needed to render 'space' pictures in real size like this

so you can switch off the atmospheric scattering and get a space vacuum.
If you render such big scenes, you should adapt the ray nudge and set it bigger. In this scene i used 0.001. Default is 0.0001
With atmosphere medium you can set up an atmosphere around a planet.

[dagobert]

ho do you set up an atmospherique paterial in blender?

[Kram1032]

^by clicking on extra atmospheric
Everything will be generated for you.
But the point indeed is, it's out of atmosphere.
This system can also render things inside atmosphere, but SmartDen didn't really add that option...
(Extra Atmospheric can be off. Then, it doesn't render the sky from outside but from inside. I'm not sure, if you then would see the moon, though... hum)
I forgot, that it works like that.
So, you'll have to hand-edit the igs and set extra atmospheric to false...
