Just amazing work. Nice to see you use Corona on this awesome project, I hope this gives devs a lot of feedback.
By the way, wouldn't you love to have Cryptomate in Corona so you don't need to do all the masking by hand. Maybe mention that to Ondra ;) ;)

Clients making constant changes?¿? What are you talking about? That never happens XD
I know form personal experience that they always complaint about the camera angles, the lighting and the color of their product.

Some feedback. Love the shot trough the doorway, that looks really nice. In general I feel like it might be a bit to dark, specially since the interior is black.

Really locking forward to see the final result on this

Really nice stuff in here. Keep going with this, it looks like your having fun.

PS: Would love a tutorial on the scanned cloth in substance.

The survey seams to be closed down, just mentioning it in case something isn't working.

We have been using Corona in a production environment for about two years. I remember playing with the Alpha version back in 2014 and I'm following the development closely since then.

The most important aspect for me is the simplicity of Corona. It has all the tools that you could want (there are always things we dream of having) and they work very intuitively. The last time I used Vray I almost got a heart attack. It seams like I always have to battle around with Vray in order to get the result I want. For us the UI is an important part of Corona, the simple framebuffer and the ease of use for lightmix, makes it a great tool.

Simply put, we get a consistent experience out of Corona that we never really had with Vray. That doesn't mean there are no bugs and that things go wrong ;D

Hope this helps

There is also the current issue of 10bit output being restricted to professional cards regardless of physical input in monitor. nVidia gonna nVidia. I wonder if HDR will force them to reconsider this stupid policy.

This has changed. As you mentioned HDR forces them to output at higher bit depth.
But they are not stupid XD it seems that you only get 10 bit when playing games. So basically it only works when launching Direct X.

So Yes, you still need Quadro

The site looks amazing, specially the Home Page XD
I have one concern tough, what is with the minimum Black value. Corona Color Picker tells me it's 0. From what I was taught you should never use 0 as Black. Am I wrong or did I miss the point??

As for colors, I have a bunch of RAL and NSC colors I use for my clientes. They are all in the furnishing business, so for industrial purposes RAL and NSC is used a lot.

Reading about the color checker reminds me, I have to shoot images of marble textures. I am a bit scared since I'm not sure I'm doing this right.
So I have a full-frame camera with 36 MP, unfortunately that is the max I could get. Would have loved to have a medium size CMOS, but that is to expensive.
Everything is set up, have a color passport, 5 mm lense and remote control for the camera.

What would you suggest I do with the images I get from this. Do I need a camera profile? or will the RAW files be enough to work with?
Would love to here some input form you. Thanks

General CG discussion / Re: best mouse for 3ds MAX
« on: 2018-11-29, 09:59:44 »
Yes Logitech is super expensive. And it has uncanny "feature" of stopping functioning eventually, I used to replace Performance MX every six months once...

I've been testing for past year and half instead this: https://www.microsoft.com/accessories/en-us/products/mice/sculpt-ergonomic-mouse/l6v-00001

It's something of in-between, not quite vertical, though highly angled and it forces your wrist to be elevated, which I consider the more important part of equation, this should avoid the pain relocating to further up.
I used to have terrible pain, couldn't work every third day. That is all gone, though this mouse requires bit of an effort to use eschewing some comfort.

This is the perfect thread I have been looking for.

I have that Microsoft mouse and keyboard. To be honest, the keyboard is great and feels very premium. Of course it takes time to get used to, the keyboard far more than the mouse.
One cool feature of the keyboard is the numerical keys that are separate. I have them on the left side. So I type in numbers with the left hand and use the mouse with my right.
This is very convenient, of course you have to teach yourself typing numbers with the left hand. I'm a right hand guy, so it took a while. And you have to change your system from coma to point if your using european annotations. This is so you can use the point from the numerical keyboard.

As for the mouse, it is failing. The left click is only working when hitting the upper end of the button. So I'm looking for a new one. And the keyboard has some F1-F12 keys that get stuck form time to time. For me, the mouse is alright but it's far to small for my hand. My hand is taller than a 6 inch smartphone, so you have a reference.

I want to get a real vertical mouse but most of those you can't program buttons and that is a NO NO.
I gess using a space mouse would be an option but I don't really want to spend money on that. Apart from yet another thing on my desktop, there's simply no space.

So this Logitech MX with programmable buttons looks great. I just need 1 or 2 buttons for pan and zoom.

If anyone buys it (me for christmas ;) share your experience.

BTW I never had any issues with pain even before the Microsoft Ergonomic mouse, it is simply to prevent getting hurt in the first place.

Thanks for the comments. As for the frame 4, unfortunately, the client's craving for several years has been a rule that if the client wants to hurt himself, I do not quarrel with him. Perhaps in my free time I will come back to this project and I will improve this staff plus I will make night shots. As for white, it gives a parameter between 190-200. always tests albedo and especially if I throw in a vray model

Clients hurting themself is unavoidable XD Every time I use vertical tilt or camara shift, I think about the real world camera and lenses someone has to have and I realize that it would be almost impossible to get the same image. The funniest thing is when your client wants one thing and the art direction wants something else XD

I don't think that's stupid idea at all. Devs already mentioned that they want to make involve GPU for certain tasks. Maybe denoising can be one of those tasks. On the other hand, if both denoising options would operate on GPU, that might mean that workstations with weak graphic card might be left without option to performe denoising at all.

I guess the world is not perfect XD

Maybe on first use Corona can find out which one is faster the CPU or GPU and than set it as default.
Of course that means more development for Corona, Denoise for CPU and GPU. So I guess we stick to CPU for now.

Thank romullus

Just read the helpdesk. Learned something new XD I already new this but I never can remember.

But about speed, I already talked about this. Could we not get a GPU Precise DENOISE. Would it be faster then the CPU one we have now?
Or is that a stupid idea.

I think it's yet another example of RGB-sRGB confusion. IsmaeL is probably talking about sRGB and you're thinking in RGB terms. 230 sRGB = 203 RGB, so both of you are right :]

Ah, right! Thanks.

That's definitely something I need to read more about...

Are you using the Corona Color Picker, than it is sRGB or better yet, Gamma 2.2 because sRGB is a colorspace and Max does not handle colorspace. But since sRGB has a Gamma of 2.2 and whitepoint of D65 we commonly say sRGB.
If you use the Max default picker than you work in linear space with a Gamma of 1

Corona Color Picker max is 230 maybe 240 for snow

Max Color Picker max is about 210

In fact, the CoronaMtl shader comes with a diffuse color of 180 sRGB with is 119 linear RGB, and that is the standard you use to test exposure. So by default as a reference a CoronaMtl in Override is very dark.

I need help / Re: Simple interior lighting
« on: 2018-11-28, 10:37:23 »
Yes, portals speed up calculation. In fact, in Coron it is not like in Vray, you won't find the portal inside the lighting section but as a material, because it does not add light into the scene.
Although I think it is still true that the portal will help the light to get inside the room and thereby add light (this was true 10 years back XD) but not lighting the scene itself. So only using a Portal won't do anything.
You can even use it as a submaterial, this is great when using a box as room and using MaterialID to add different materials and a lightportal. So you can change your geometry in one Editpoly and the lightportal will fit perfectly.

And YES you should always use lightportals, although in the helpdesk they tell you that there are circumstances you don't need them. Many artists have done tests to establish that you always need a Portal.
Unless you use Vray Next with an adaptive dome XD

In my small test nvidia GPU denoiser denoised my image better but also lost a lot of detail in the image. Especially textures like wood grain etc.

Corona standart denoiser (CPU) did a better job, but was slower. I think its  very nice to have both.

I used NVIDIA denoiser on my white renders which is a miracle. I had my clean white renders in seconds. :) Using Titan XP. Anyways both are great.

Thank you very much.

I thought that the Denoiser always has been GPU based, that is why on my old Quadro it is slower than on the new GTX 1080.
Was I wrong???

Nice work. But YES that vertical correction does look weird.
Just one tip, lower your white albedo. That boat and the lights are to visible in the images.
Max white I use inside on a wall is 230 sRGB so you can get away with 200-210 on that boat or even lower

With Coronalight there is no problem at all.
If you use Environment make sure to put a Portal inside the door.
As for selfiluminationg materials, they can be used without to much trouble when you have to creat a visible light. Like a Lightboulbe. Then you creat a coronalight to light the scene and use your selfilumination only as visible light. In other words, use a CoronaSwitch material with a GI material that has no selfilumination. This prevents calulating the lighting form that material but it still shows up as a lightbulb

The only problem I see with OCIO is that it is only a view transform, so you can't save the image from the VFB with transform applied. This is the annoying way Vray has of doing things.
I guess in Corona you could just save the image as is shown in the VFB or make the OCIO apply internally in some advanced option, so people don't mess with it.

What is clear to me, is that we want ACES tone mapping applied as a standard, just like in UE
