Living Room

[lius86]

Hi guys,

A quick test of Corona 1.01.

Finally no crashes while working on this, (the 7.2 was crashing a lot), but, even if i had 3 portal on the apertures, and Albedo values corrects, materials correct, and even tweaking some render settings, i couldn't manage to get more than 1 mln rays.

I left processing one full night, and i stopped it after 200 passes.

lighting made with 1 HDRI, with 0.75 gamma. It has been very very useful, activating the IR while rotating the HDRI for lighting, just amazing.

Thanks,

Luca

Hi, the scene could probably be optimized further. Can you show where you placed the portals? I think the most correct way would be like on the picture I attached (green = good, red = bad). There shouldn't be any objects behind portals. Someone correct me if I'm wrong here.
How did you add the background?

What were render times like?

Hi Maru,

Please see the attachment for the portal position.

The background was a simple plane with no shadows, and off to GI.
I am sure that we can do better, in fact i was quite unhappy about the rays number, but even following your guides I couldn't solve it.

I tried to add another light in the scene, but it didn't change much.

Render times were good, I would say around 4 hours for a decent result at 3k resolution.

Thanks,

Luca

Hi Maru, 

please see attached, the render with portal lights as you suggested.

How is it in comparison with previous setup?

Why do you need portal for such huge opening at all?

[racoonart]

Portals don't have to be small to be useful. Even if 20% of the room is a portal it's still better than sampling the full 360x90° for environment.

no difference, same number..
Just to let you know, i am doing a close up view, and i made a massive hole in the ceiling with a portal plane applied, and now i get more than  2 mlns..

Ok I did some tests (attachment), the difference is marginal indeed.

Thanks Maru for the help.

This is the closeup view with more rays.

If you want, I can share the file with you, it's just a scene test for me.

Thanks

The horizon line, in the river,doesnt match on the two different windows. Besides that i think its really good ;) congrats!
