Work in Progress/Tests / Re: romullus's wips

« on: 2014-10-24, 13:05:25 »

Was playing with growFX demo - what a cool plugin! A bit hard to learn, though. Anyway, created this strange thing, now it's time to learn how to create some trees, before time limit runs out :]

[Max] Resolved Bugs / Re: interactive rendering - crush 3dsmax (build 2014-09-12)

« on: 2014-10-22, 12:53:57 »

Dev team is working hard on fixing interactive rendering bugs right now. There's little point in reporting issues with older builds, i think. It may be already fixed in newest one (10-19).

I ended with GI/AA - 64 and LSM - 0,5. Is that a good idea?
It might be. Could you post some render and viewport?
Buckets with adaptivity pay off when you have large flat areas that refine fast. So when you are rendering without adaptivity, Corona will sample those good pixels anyway wasting time. In hard noisy situations adaptivity may even slow down rendering because it will add lots of samples in those places. At least that's how I think it works. :)

Unfortunately, there isn't single flat area in my render. I did some tests yesterday with 3/3, 2/4 and 1/5 settings for adaptivity and contrary to my expectations, settings with more initial samples and less adaptive passes rendered fastest. So you might be right, maybe my case does not suit for adaptive sampling very well.

Anyway, if you use a lot of direct lighting then I would try using default 16 for GI and some higher values for LSM (like 6 or 10 maybe) not sure about sss sampling though. I guess default 16 for gi should be ok.

It would help if you could post a screenshot of your scene setup and maybe also some screenshot from rendering.

If im not sure where is most noise coming from I disable both gi solvers to see how much direct lighting really contributes to the scene and if most noise is from GI or direct light.

Direct light is cleaning very fast, most of the noise is coming from translucency. That's why i reduced LSM.

Anyway, i rendered test sequence over night with bucket engine. Settings were GI/AA - 16, LSM - 0,5, Initial samples - 3, Passes - 3. With some denoiser treatment in AE it came out quite acceptible.

p.s. sorry for lack of screenshots, but i don't think they woul be useful in any way. It's just single object in open space - there's almost no indirect. Only direct, reflection and translucency.

[Max] I need help! / bucket engine adaptivity

« on: 2014-10-21, 23:06:44 »

I'm trying to find best settings for quick animation. Decided to give try to bucket engine in hope that adptivity will help to reduce render times a bit. But i'm little struggling with adaptivity settings. I tried 2/4 vs 1/5 (initial samples/passes) and it gave me almost identical times. Does that means that adaptivity hadn't kick in? Should i rise adaptivity treshold? Would that help? I don't want to increase samples or passes more, because i can't afford longer render times.

And question number two. My scene contains much direct light and almost no indirect and also there's heavy use of sss. Initally i thought that decreasing GI/AA would help, but it turned out that image appears even noisier. I guess that means SSS needs more GI samples, right? I ended with GI/AA - 64 and LSM - 0,5. Is that a good idea?

Why it took me so long?

You need to render with alpha 4 benchmark utility if you want to compare render times. Look at first post of this topic.

[Max] I need help! / Re: Normal Map + Bump (B/W)

« on: 2014-10-20, 19:24:36 »

There's no additional bump in CoronaNormalTex map. If you're using max's native NormalBump map, no wonder why you're getting wrong results. Normal maps should be connected via CoronaNormalTex only.
