" currently use both, and what I am gonna say, I am happy user. " juraj, can you explain some more? are you still using the old method on corona or are you taking the data from megascans or something else on your shaders?
Has anyone tried marmoset on arviz inteior scenes or so?

You will not have much sucess with Marmoset on any scene really :- ) It's asset previewer.

No I am using everything as is now regarding rendering. I am happy user of CryEngine, that's what I meant :- )
Btw I am not in megascans beta, but I might write them to see if they would consider me. I don't think it will be live for public until after summer.

I remember Octane dev saying the same few years ago. Might be reason why it's much faster than the mixed CPU-GPU solutions, which only show negligible speed improvement by adding GPU to mix.

So than we're stuck with 4000 euros costing Teslak40/Quadro6000, only cards with 12GB of vram. Really amazing...
Are most GPU-renderer customers even aware of this fact ? Or they just see "100x faster!" and insta-buy.

The Disney implementation is pretty cool; I'd love to see something like that in Corona. But most of the "omg pbr!" features are actually already in Corona, and have been from the start.

Of course. The PBR is revolution for real-time, because previously, there was no physical correctness at all. But the benefits are still here even for classic off-line renderers.
Have you ever seen Maxwell ? It's clumsy and odd, but it comes really closest, with controls for 0 and 90 angle incidence, roughness affecting both diffuse and specular reflectivity,
natural layering,etc..

To me it's way more natural once you dive into it, and soon there will be a lot of available data for it (measured values for everything, prepared textures,etc..) because real-time PBR market is so much bigger than
visualization market (which quite frankly, will be the only market for Corona), that it would make future life much easier for everyone.

It would also allow for easy translation of scenes to real-time, something that will happen a lot soon. 80perc. is just different controls, so that's why alternative shader is imho viable option. And the rest 20perc. allows
for easier and more precise shaders for specific materials (mostly metals).

so unless you have at least Titan Z with 12GB RAM, there's not much of a chance to render some more complex scenes.

TitanZ has 6GB, it's dual-chip unit. And that makes this renderer just as obsolete to me as every other one, until shared memory becomes available and proves to be efficient (which might not happen).

I wasn't that impressed here from start...seems odd way to choose. Maybe they're targeting very broad general market with those "all autodesk shaders" (because I don't see how that would really interest pro users).

So it's just about having more choice for the specular reflection model? Because that is literally the only difference between the new GGX (etc) materials and Corona's material.

No, that's like 1/10 of it...but it's the easiest feature to implement. Already does a big difference to me.

Maybe Vic's original post seemed confusing because he linked PBR very closely to real-time (Marmoset), where is greatly integrated but it's not really tied to it in anyway.

This is my favourite article on it which I keep returning to, maybe that better describes it ?

YES

YES and YES !

Real-time engine nowadays (Unreal 4, CryEngine 3.6.4 EEAS, I use both at the moment) have so much better material system than offline rendering has, that offline rendering looks like prehistoric legacy almost :-).
(with exception of VFX houses of course, both ILM, MPC and all the big boys already using this new model).

I already asked Keymaster if he's willing to implement advanced BRDF models (like GGX, ABC or ShiftedGammaDistribution, currently all as plugins by Sergey Schliaev, although GGX is already integrated in Vray3.0).
I understand he has little time and there might be more important things (not to me heh), but imho it's much better to differentiate from others than slowly add features that all others already have. I don't want a better clone, I want revolutionary product instead if I could choose.


Btw Maru, the shaders still respect any sort of look, even completely stylized or unrealistic, they just make the creation of it vastly easier, and more natural. At the moment, it's absolutely odd eye-balling, where I dare to say, 90perc.
of users do not even no what value should actually be in reflection slot or how to even create TRUE metallic shaders. Quite frankly, all metals and plastics out there look like shit to me.
Did you even look at those shaders ? It's not harder, it's not scientific. It's logical and superb.
IMHO it's definitely a time for revolution, I don't understand this harkening to original concepts and still using the same material as Scanline. It bothers me so much than I contemplate just sticking with real-time by end of this year. To
me it's already evolved enough and it's evolving by master space speed.

Did you guys read the original post ? Did atleast 5 minute of research ? Every single post seems somehow off-mark to me.

Well for me Corona materials are already using this kind of knowledge.

Not really...not in any way Vic outlined.

but setting the limit and restrictions would hurt the creative process of special effects.

There are no limits or restrictions. How did you guys translate it into this conclusion ?

Well, skilled artists use canvas & brushes and are free to do whatever expressionism they want ;)

And it's working amazingly for everyone.. I hoped the "it's the artist, not the toolz" days are long gone.
We could have just stayed with Scanline.

My idea would be like a separate, experimental shader to use alongside.

Of course 32gb is mainstream

CGI Hipsters :- D no really, this lifted my mood.

Well, as others said, no qualm between Corona and exteriors.

I would just add that, there are still considerations one should take into account. Basically, any scene that will render under XYZ, should render just fine here, but, if you're coming from rather well developed, tweaked biased engine,
you might be doing things that more strict renderer like Corona (or any other path tracer) is not so forgiving. Where previously, you could interpolate some detail into mush, or adaptivity would solve it, mistakes here could lead into stuck noise,
but it really isn't fault of the renderer, it's the fault of user in such cases more often than not. (i,e. 1000 unnecessary lights, hidden/obstructed by complicated geo, caustic glass where not needed,etc..)

I would recommend not touching controls of sun/sky, and instead lowering exposure to about -5

But the intention is to create different ratio between Sun:Sky, so one has to alter one or other. If I use sun, I also use it purely in much much weaker position, no need to simulate alpine strong light.

Thank you very much! Sure, I actually used a HDR from Cg-Source (might have written wrong before, sorry about that), but the sky I used is called "cloudy_sun44deg_0086-01".

Heh, I wondered if it was typo....because CGSkies is like the...worst trash possible, while CG-Source is heavenly. In fact, no other should even be considered at all, if CG-Source was 10points, everything else would be 1-4 top, not more.
And I've tried every on the market, hundreds...

I am not compositing myself, but when I do work in linear space in post, I didn't honestly notice a difference between doing so in Photoshop and AfterEffects. For compositing lineary you need either Photoshop Extended (I think CS4+, although I only ever had CS6 from start) or Photoshop CC, both which allows layers in 32bit mode(only time PS will allow you to load Linear RGB color profile, and will do so automatically if opening linear file, .exr/.hdr). I don't see why any problem would arise after than.

Every small freelancer who ever bought Boxx is idi**,...ok, person who hates his money. Check some threads on cgarchitect.com forum, HW section, we discuss it there with Dimitris and bunch of guys to death quite often. There you can find almost 20+ virtual builds for any sort of budget from 800 euros to 8000 euros, just suit yourself :- ) Budget is the only limiting thing. To be honest you can built excellent workstation for as low as +/- 1400 euros and you would be completely satisfied compared to what you currently have.

Always buy only what you need :- )

Is anyone brave enough to do that jump :- ) ? With zero plugins support ? I contemplate to skipt 2015 and get maybe 2016 instead, for which 2015 plugs will be compatible again, so no hassle.
