Help me render my scene

[ahmadun]

Is there anything wrong?
No one finished with my simple.igs
My light source is a sun, (environment=physical sky+sun)
And yes, i exported it from Blender.
The glass is in a diffuse box, but there's only a "very little window" on that box.

I hope you put a Exit Portal on this little window to speed up the rendering massively

[zsouthboy]

ahmadun, can you attach the .blend file for one of us to take a look at?

[ahmadun]

This is...

[zsouthboy]

Desperately you need an exit portal around the "window"

Why are you using sun/sky on this scene? Little sky will make it through the window anyways, and the sun could be better approximated with a small meshlight.

Surrounding the entire scene with a phong box is killing performance as well - if you want the floor to reflect the glass, just make the floor reflective. Because light rays are taking forever to terminate (since they're specularly bouncing and bouncing and bouncing), your scene is rendering very very slowly.

Not to mention that you have SSS on both the glass and the liquid, which will slow things down . . . if you need it, try it just on the liquid. And the scene's scale is about 10 times too big. I don't know if this would slow the render, but it will result in some incorrect calculations.

Also, your Supersamples are set to 3, when no more than 2 (default) or even 1 are usually needed. The Max depth is set pretty high, too.

It'd be fun to do a comparison between the "inefficient" version of the file and the fixed version.

Like see how many samples you get after 3-6 hours on the first one, then on the second one. Or maybe I'm the only one interested by that

[PureSpider]

Nah I would like to know that, too!

[Borgleader]

Well if someone can give me an igs for both fixed and unfixed versions of the scene I'll do it

[ahmadun]

Thanks for all for this
