PBR

here you go.

http://polycount.com/discussion/155096/substance-designer-tutorial-list

Cool thanks anon.

its a real time meme unfortunately. The only way to fly is with toon shading.

>>551455
honestly realism is a meme. it always gets outdated so quickly, but the designs with their own style look good for much longer.

there are ps1 games that look better than mass effect andromeda.

however, the layman doesn't understand art and merely responds to high resolution textures and high poly counts and last decade's run of the mill shaders.

you have to realise we're at the infancy of the computer graphics, realistic games look outdated fast because we're improving fast

>>551464
>realistic games look outdated fast because we're improving fast
and yet nothing has changed since 2008's Avatar. The industry is dying.

>>551468
because avatar had gorillion dollar production value and looks amazing

what's your point?

>>551469
almost 10 years have gone by and theres been no progress. The other day I bought Avatar on blu ray, the 3d version and watched it on a 3d tv and it was still the best looking cg ever made and the 3d stereo put it over the top. The industry has grown so stagnant...its....pathetic...

>>551468
that's because the industry is saturated. why hire the best man for the job when you can hire some average dude that will probably will work mostly for free and do a shit job and has no idea how next gen looks and feels like

>>551470
it's "stagnated" because avatar already looks realistic, obviously you can't go beyond that

also this thread is about realtime rendering and that hasn't stagnated at all

>>551461
Hey thanks dude I'll give this a good watch.

>>551472
it has, play a few games son. Everything looks like crap. In substance you only have one main object and various subjects to calculate, not an entire engine with physics, algorithms, etc.

Tl;dr you're retarded

>>551475
no it hasn't, realtime rendering capability is entirely related to hardware and as long as hardware is improving, rendering quality is improving

tl:dr stop posting

>>551476
according to that logic we could have todays graphics in the Apple II era by just having enough of them in the same room. Please kys,

>>551456
a Chinese cartoon forum doesn't like realism.
what do you know.

>>551477
yes?

you could have flawless realtime graphics if you built a supercomputer to that end but it's not economically or otherwise feasible so it's not done

just stop posting man

Nothing memey about trying to have materials that look the same way across different software.

My only complaint is that things made for UE4 look like they're made for UE4, and it's kind of leading to a homogeneous look to 3D art (especially on Artstation)

>>551877

Feel free to create your own rendering system, then. I'll stick with PBR since it has somehow become a standard very quickly. If something better comes along (from you or anyone else) and it sees widespread use, I'll start using it.

I don't care how materials are rendered as long as they look nice, are believable in the context of the scene and load quickly.

>>551881
its not the standard and it looks like shit. Look at >>551880.

Trash pushed by that autist Tim Sweeney

>>551883
I like PBR. I'm glad it's becoming widely used, it looks much better and realistic than old specular shading.

>>551883
So you're saying something like this looks bad to you?

https://sketchfab.com/models/5e53e0cc5d554388a3b2c2ae551b406c

You're free to believe that if you want, but good luck convincing potential employers that PBR looks like shit.

>>551885
it looks fucking awful and not realistic at all. Id rather have a painterly look. I could gaf about "potentiul employers" since I have a job

>>551886
>painterly look

What does this even mean? Stylized textures? PBR is just a method for rendering. You can still have a "painterly look"

https://80.lv/articles/kraken-attack-stylized-approach-to-pbr/

I think you're extremely opinionated about something you know very little about.

Artists have been working for millions of years without "realism", its only recently that idiots like you have became obsessed with it. Its fucking terrible since computer graphics does a shit job at realism but obv fucking autists dont care.

go back to your cave to make "realistic" renders of metal balls to post on artstation and jerk off with your buddies like the autistic manchild you are while I work a real job over here.

You want wax? Let's talk about the specular/gloss system.

>>551923
i hope you realize spec/gloss is still in pbr, anon

>>551925
Yes, but it's not necessary to the workflow. I've only used it while working on eyes and a couple of wet textures.

>>551930
but spec gloss is literally the way pbr works, metal/rough just simplifies it with a binary, catch-all parameter

>>551932
I'm just using the nomenclature. I've only actively used a dedicated specular or gloss map in a handful of projects based on PBR. You are right in the sense that it's just a different approach to spec/gloss, or whatever other terms we use to describe microsurface and reflectivity.

>>551944
Actually they do.
I love both.
People who believe one is "better" than the other are just retards who confuse objective truth with personal preference.

>>551987
but there is an objective truth, though
PBR is a meme, shills pretend it's more realistic but it's not even remotely the way the physics work so it cannot be.

>>551988
shit coming out of my anus and falling in your mouth is an objective truth

>>551988
The objective truth is that no shading algorithm works the way physics works, even the notion of a BSSRDF is an approximation. The only fundamental truth is whether your approximation to gives good looking results with an efficient workflow for artists and rendering engines.

https://www.youtube.com/watch?v=j-A0mwsJRmk

So that's what PBR is all about, it's easy to understand, easy to implement in software, and gives generally good results, so that's why everyone uses it.

>>551988
people don't pretend it's "more realistic", the reason PBR exists in the first place is to make it much easier to produce materials that approximate real surfaces without having to have a spreadsheet of specular values

>>552014
people use PBR because its a buzzword, like adding volunteering to your resume even if you never did. All you need is ggx spec, a cubemap with hdr values, and some filmic tonemapping and ssao

>>552019
that's great if you're a forever alone in a basement like you, if you're working across a team across an industry it's better to have a standard

>>552026
PBR is the standard now and for good reason. You can try managing a workflow involving HDR cubemaps, tonemaps, SSAO settings versus metal and roughness values which always give the same result.

For what it's worth, a lot of people thought SSAO was a "buzzword" and look where we are now.

>>551975
In what way does it limit you?

>>551975
But PBR can look good. So it is good, right?

If you can't make it look good, that means you aren't competent as an artist.

PBR != using metallic channel

>>552080

>>552082

PBR means:
> Materials should obey conservation of energy and should be possible to derive from physical first principles. (no Phong)
> All materials should be able to exhibit specular highlights. Nothing is 100% diffuse. (no Lambert)
> BRDF is used as basic principle for rendering equation. (Majority of the interesting surface detail should be contained in a roughness map)
> Specular highlights follow the laws of physics. (Unless the material is a metal, materials should use uncolored specular. Highlights obey Fresnel law. Because reflections are physically the same thing as specular, they are not treated differently in the render engine.)
> Additions to the BRDF (SSS, transparency, emissive) should also follow physical principles. At the very least they should not violate conservation of energy.

Skimmed the thread; if you'll notice there are only 18 original posters but 120+ replies, your answer is obvious - Autism.

PBR has been around for a long time, however PBR is relatively newer in game engines. It's definitely not a meme as we use it all the time in renderers, but that's just the 4chan mentality. 4chan is just filled with a bunch of autists pretending to work in the industry, with a handful of actual artists who work professionally. Keep this in mind when you browse /3/.

>however PBR is relatively newer in game engines
Not an argument since PBR was specifically created for use in game engines

>we use it all the time in renderers
False, the majority of render engines only support the outdated specular map workflow

> 4chan is just filled with a bunch of autists pretending to work in the industry, with a handful of actual artists who work professionally.
So which one of the two are you? Hint: you got no idea whachu talking about

>>552158
>False, the metalness workflow exist only for a couple of years now.

PBR is not about having a metalness map. Metalness is a rendering optimization used for realtime engines. It was removed in Renderman 21 because it's useless if you don't care about texture compression.


>Not an argument since PBR was specifically created for use in game engines
PBR is a reaction to purge old school phong/lambert/blinn shading invented by computer scientists with no consideration of physics.

This book is what made the term "PBR" popular. It's from 2004. http://www.pbrt.org/

Realtime engines didn't (or couldn't, due to hardware limitations) adopt these ideas until much more recently.


>False, the majority of render engines only support the outdated specular map workflow

Except it isnt, your supposed to put that color in albedo, there actually isnt a thing called "specular" in real life, its just a fake non-physically corect effect.

>>552164
Specular in this instance refers to reflection of light or an approximation of it. In both cases for metals like gold the color you see comes from the colored reflections, not the albedo.

Gold is one of the first materials you should learn and understand, I think you skipped a few things while learning.

>>552166
"gold"
looks more like urine tbf anon

>>552166
Whatever dude, the nice thing about PBR is if your not sure about something you can always just use one of the many existing substances, no reason to reinvent the wheel every time you texture something

>>552164
Wtf are you smoking, lol. Where did you learn that?

Specular = completely reflected light
Diffuse = light absorbed by the material and re-emitted.

Two physically destinct phenomena. That's why specular does not change the color of the incoming light, and also why diffuse has no directionality. None of this has anything to do with microfacets btw.

Lambertian reflection is physically based, it's the simple phenomenon that a surface is less bright as it is rotated away from the camera. It's used as a basis in basically all CG. But there's no such thing as a 100% pure Lambertian surface with no specular component. Even Vantablack reflects a tiny bit of light.

I'm not, I'm talking about UE4's shitty internal DDS block compression, makes it literally pointless to work on texture details.

>if you're talking about bloom it can be turned off
That's not the point, almost every single engine that was released in the last 5 years has better bloom. That shitty bloom was a telltale sign of UE3 and now it's becoming the telltale sign of UE4.

>Lambertian reflection is physically based, it's the simple phenomenon that a surface is less bright as it is rotated away from the camera
humm maybe I'm understanding this wrong, but if the surface takes the camera into consideration, isnt that NOT physical (as in the real-world behaves) ? or is it some real property like fresnel or something?

> Even Vantablack reflects a tiny bit of light.
This is a good example! But isnt the "reflected" light only bounced light? I mean, in the sense that if one was to do that material in 3D, the diffuse would be something like 1/255 and the reflection/spec 0/255. I get the feeling that the two principles get confused sometimes when materials are designed.

yeah no I've pretty much done all the research an amateur can do (understand) on quantum mechanics, it's just no really relevent when it comes to create CG materials, at least top of my head I cant think of any example

>>552332
if you don't understand basic quantum mechanics I don't see why anyone from /3/ should help you

>>552335
can't you read?

I'm just not gonna dig into the deep mathematical realm of that stuff

btw, if you think you fully understand quantum mechanics, you're full of shit friendo

> OP asking for PBR stuff

Shit man, the /3/ community struggles to have basic knowledge on PBR, anatomy, color, composition, etc. and you think they have any clue of what's going on with the tiniest components of the fabric of reality? Get real

>>552330
I'm going to explain to you PBR, but first we need to talk about parallel universes.

>>552323
Psh alright. Lol
