Hi All,
Playing with the Linear Response curve. I likey! Definitely much easier to get more accurate colour representation and shadow depth. Feels like I'm also seeing way more light temperatures. Not to mention much more room to play with adjustments in post. Especially when saving as an EXR (32bit).
So no biggie. Messing with a tiny dining room trying to find decent settings. 98% straight Octane, 2% minor targeted dodge and burn in post.
Info:
Octane Max Plug 2.11.1
-PT 6144
- Filter 1.0
- caustic blur 0, GI clamp 5.0
-gamma 1.8
-hotpixel 0.4
-camera response Linear
-diffuse bounces 8 (coherent mode)
- 2+4 Titans (2 local, 4 net)
- 1hr. 27min.
Best,
O

really nice!
I've been trying to wrap my head around the linear workflow lately and having a bit of trouble. Would you mind quickly talking about your workflow so I could get a better understanding?
are you supposed to adjust your texture's gamma in photoshop or do that in octane plugin? if adjusting in octane plugin, does each texture get gamma adjusted individually in their texture nodes or do you just adjust the gamma of the camera and leave textures as is? when saving images is there anything specific way they need to be saved? Sorry for all the questions but i'm struggling with understanding everything and it seem like you understand well.

Can you render a comparison with the default 3ds max plugin response (agfacolor futura...)?
Most of the time I'm using the default response. It has a little bit more contrast than linear but has this green/yellow tint and you always have to fiddle around with white balance.
Would be nice to have a response curve that has a neutral white point but with more contrast.
Are you guys using all of the response presets? I could easily live without most of them and have some more neutral ones...
Nice render btw

Great work!! It looks very real and sharp without being "bright white"
p3taoctane - Haha, thanks man.
itsallgoode9 - To be quite honest, it's taken me years to 'try' to understand LWF. (I still don't think I get it). I'm not sure if working in Linear Camera Response is the same thing. However, in my workflow, I only adjust texture saturation in PS. I adjust overall image gamma in camera to get image contrast. I usually leave the texture node gamma as default (2.2), but occasionally 'fine tune' the texture node gamma if I want more contrast in the individual texture. Usually we save out images as 32-bit TGA, but I'm now enjoying the wider flexibility of post work by saving as OpenEXR or HDR.
neo83_gr - Thank you. I have "highlight compression" cranked to 1.0 and filter set to 1.
RobSteady - Comparison below. I kept the exposure and white balance identical to the original render to make comparison easier, but had to crank down the gamma to 0.8 on the Agfacolor (film) curves to compensate. The last one is Linear with the same gamma as the Agfacolor curves. The colours of my actual textures in photoshop are identical to how they appear in #1.

O

man, Stop posting Photos in WIP sections (it's ment for renders & WorkInProgress shots =DDD
Joking, Oli! Nice to see You here! & have to say, very beautiful shot You're crafting here! =)
small question though: How You managed to get noise free image using those lamps with filaments?

Very good question. All lights in the scene are emitters. 100,000 samples per emitter. Then there is a giant doorway size emitter off screen to the right. It is blasting blue daylight into the room as well as balancing against the dining room window hotspot.

Thanks for reply, Oli.
The mood,
that warmer/colder mix is very pleasant!
Keep shots flowing!
