[C4D] General Discussion / Re: Physical Metals

« on: 2017-12-10, 22:00:25 »

true, my bad

edit:
But is not interactively driven?
meaning, the tag generating gradient doesn't drive the shader... it has to be done manually, correct?

edit2:
It also doesn't feel like real Physical Metal.
Need to make some comparative studies.

[C4D] General Discussion / Re: Texture on a corona light

« on: 2017-12-08, 22:59:19 »

:) hmmm... yes, you can use 32bpc EXR/HDR for image based lighting even if it's just a mesh with a texture ;)

e.g. Polygon has Corona Light Material applied to it, sample hdr used is from https://www.pingo.nu/vfxtools


& couple of other nice light packs:
- http://www.alsens.net/34234
- Lightsmith Collection from http://www.hdrlabs.com/sibl/archive.html (below, in the middle)
- it's also very easy to make your own, out of any light source ;)

although IBL is most commonly done using an equirectangular hdr image mapped on an environmental sphere (or cube...) - but lacks maneuverability with animations & interiors... so here are some extra tools for more control:

General CG Discussion / A bit about the Nvidia's AI denoiser

« on: 2017-12-08, 15:47:04 »

- VRay is getting it with v4... see it @ Vlado's YT channel

- Clarisse also (which is same as Corona, CPU engine)

- On Iray, denoiser uses ~800MB VRAM alone. (source)

The way the denoiser is implemented is, that it uses a soft-limit of 800 MB of video memory for denoising. I am saying soft-limit because in certain cases the memory consumption may go beyond that limit, but in general it is pretty solid.
Up to 800 MB might seem like a lot, on the other hand you get a big quality increase for that.

Best Regards,
Rüdiger

Yes, CUDA tech only. Working in unison with CPU. Throw cryptomatte into the equation & you get to play as Vlado does above - almost Real time ;) ... am already missing moments when i had real time to contemplate, think & make decisions on the work, it's design... but it's fine. Now more invested in conceptualization & the environment is quieter, more stable (less can go wrong in couple of minutes then in couple of hours) :D

:) no problem
Just post your scene & material settings (be sure to use correct scale & so on)
Best would be if you provide the test scene, to have facts at hand.

i.e.
Here's 8k normal map on a sphere (r=1m): Grass Cut from megascans
(from left to right) Bump Strength: 1 m, 5 cm, 10 m

« on: 2017-12-06, 15:45:42 »

Hmm, likely a bug then... IDK, but i remember there was similar issue on windows in the past. Now is fine (r18/r19).
I assume that AR/Phy/RPR or other engines work fine... ?

Nothing gets lost, just misplaced ;) Evidently... :D

Vodka went down the throat and some kind of smoke was rising... or was it steam, fog... hu, hu... hmm, can't remember anymore.
And it's getting freezing cold out here. Soon everything will be made of solid ice.

"What about PS example?!? How does it look? Which format do you use? Color profile?..."

First, to be on the safe side, in PS use 16bit tiff (profiled). You also need to be aware that alpha channel is strictly linear.
_{Disclaimer: for my taste & needs PS is too finicky, confused & limiting and so on - remnants of ancient tech ;)}

Now, on to the color science - down The Rabbit Hole* you go...
 
^{* The Rabbit Hole - Questions and discussions about scene referred, display referred, color management, pipelines, and rendering.
It all begins here: "Render with a wider dynamic range in cycles to produce photorealistic looking images"}

Have fun :)

Yup.
What? What was that? That's no ordinary glass. I guess... Could it be smoke?! Pass on?

Mind has tricked us again.

btw - i like Mikhail better

Lately I worked with animated material parameters and layered materials and found lot's of anomalys in the matrix. Do you have a bug report system, or should we just post every bug in this thread? I'm just asking beforehand.

Well, it feels better here.

Some bugs:
- IBL on the Sky Object crashes (use Sphere instead) 
- Environment Fog still disappears after first frame, also Exposure still resets
- Compositing Tag Properties (Visibility) seem to work

My personal advice from practice to those experiencing instant crashes:
Clean your installation (registries, directories, render-, camera-, sun&sky- & other settings, preferences...) before upgrading - using new build.
Since plugin is still in heavy development, code can change in a way that may cause scenes which work on previous builds to produce errors ending with a crash! Is not a must but is sure one of possibilities.
;)

enjoy

As I wrote, it depends on what you know, how you did...

You need help? Start helping...

Reveal to us your shader settings. Post what you got made.
Are reflections dark because there's no light to reflect?

;)
