CHALLENGE - Show your skills (scene included)

[cecofuli]

Hello everyone,

I'm working with an interior scene. And I would like turn off sub-pixel mapping, because I like to see nice highlight in my scene.
In this project there are a lot of transparent objects. But, as we know, sub-pixel mapping can kill our rendering time.

Here the screenshot. I tried with many different setting, from BF+LC, to IM+LC with and without sup-pixel.
But the rendering time is very high with sub-pixel off. Here the settings (4h 30 min for 1024px with I7 970...)

DMC: Min 1 Max 32
Reinhard
Sub-pixel : off
BF: 64 or 128
LC: usual setting
DMC sampler: 0.5, 0.015, 8, 1
subdivs mtl / lights 8

If you want to try with me to optimize this scene (with sub-pixel off), I have the complete scene ready to use.
Just click "render" and you'll have the same result, with my settings.
Send me the request in PM for the zip file.

I think myself and lele can have a play with this

Mmmmmmmmm, nice thread!
I will not give this one a try seeing how much time I already spend trying to make it work on other scenes, but I definitely want to hear the final words about this one!

Cheers

Little update in the file. The scene wasn't optimized for RT. Same link


--- V2 ---
(*) Change lights for RT (RT doesn't like mirrored lights)
(*) Turn on "specific focus" in VRay Camera to solve the V-Ray 2.40 DOF bug in RT.
(*) RT Trace depth from 5 to 10
(*) Set RT limit at 2h



--- V1 ---
(*) First version

I forgot to post the samples renderpass

BF+LC (sub-pixel =OFF)


IM+LC (sub-pixel =OFF)


BF+LC (sub-pixel =ON)

VRay RT CPU (I7 970 @ 4Ghz) - 2 hours

[cecofuli]

V-Ray RT GPU (570GTX) - 2 hours

[cecofuli]

LC + LC = PPT mode - 3h 30min

Have you tried SolidRocks?

[cecofuli]

BF + RT CPU + RT GPU + PPT

[cecofuli]

Have you tried SolidRocks?

No. I'll try =)

Challenge indeed, but I think I got quite ok results. ir+lc - 1h 59min



I had totally different approach than you. Vray is "almost" back in default settings, but all materials and lights have a lot more subdivision in reflections, shadows, dof etc. Some materials might have even 512 reflection subdivs.
