Light setup

[kibbycabbit]

Hello,

If I am to make a space simulation with some space crafts, what is the ideal set up for lighting?

What I have done is:
-adjusted environment to Daylight (I tried "No environment" but it wouldn't simulate sunlight)
-added space image to Sky Texture
-dragged Daylight time setting to 08:00
-adjusted Sky color to very dark grey
-adjusted Skyset to pure white

It renders too real. I mean, the shadow is pure black. I need the shadow to lit up a little.

My biggest question is, how do you adjust ambient in scene? I notice Ambient setting presents if using Direct Lighting.

Thanks for your time,
Kibby

Or.. Anyone knows a good tip & trick to get ambient lighting?

Can you list what light feature in DAZ Studio that Octane Render will recognize?

Sun & Sky environment
Surface emission

Hi Kibby,
here is a first attempt of a space sky using only octane procedurals and exported by DAZ:

And here is a couple of renders:

In general, the environment texture controls the ambient light, in this example you can change the power of the Ridged Fractal node and or the power of the Marble node.
I hope it could be useful for you,

That's a great help and I love your Space-Sky setup. Thank you!

I begin to realize everything in Octane works like real life. We can't fake the light sources (i.e.: ability to hide the surfaces with emission).

Octane has Sun-Sky node in Environment. I am wondering if it be possible for us to have more than one Sun-Sky in a scene? If so, how? A scenario where a spacesuit stands on ground looking at sky with two suns -- receiving two shadows.

mmh, since is not possible also in standalone, the only way that I see is to have a very good HDR with sun used in conjunction with the physical sky and with importance sampling active, in this way you can have two suns, or even more if you bake the HDR in standalone
