Directlight / AO

render time 12 min. 1xgtx680 4gb

I used a mesh light outside window. 5 cm radius sphere with blackbody emission for simulating sun.
Environment is 255 255 255 white color only.

AO distance is 3

Why not use real sun.

because it gives the blue shadow

Hi wisemanxxx,

can you make a quick test shooting a wider part of the room?, I'd like to see how becomes out the ceiling; the most difficult for me working with AO is that the walls and the floor are ok but the ceiling comes out darker (slightly gray) or a totally flat white (without any gradient due to the shadows).

I Like a lot the idea to fake the sun (and the result is ok), there must be taken lot of tests even in PT or PMC...maybe in some situation it can become handy

Cheers, Paolo

Because I don't want bluish or yellowish environment.

I don't use PMC or Pathtracing methods because they take so much time.My will is take some animation shoots with Octane Render.PMC or PT are impossible to use with animation.Especially you've hot only 1 or 2 graphic cards. Infact If I use this methods I must put some extra illumination elements in scene.Because in real world you can't take a good shot when sun shines from windows or openings without extra illumination.Direct light method automaticly lit all scene like put some extra illuminations I like it.

If you set your scenes with DL/AO please share your experiments too.

cheers

Why do you think that blue is bad? When I was studying I used mental ray mr sky to simulate the glow of the sky. Excessive blue in direct picking can be neutralized in a film camera.

This render with the sun. I think this light quite nice and there is no excessive blue. Isn't true?



As you can see - in real photo shows a bluish glow.

Blue is very bad!
