🧵 Yafray
Anonymous at Tue, 23 Jan 2024 19:18:24 UTC No. 971625
So, I had previously restored Blender 2.49 to run on Debian 12. Here's the patch if you want it:
https://sourceforge.net/projects/sn
And that's great but I was wondering where Yafray went because back in the day I remember some of the Yafray stuff being quite impressive.
In the UI code the button to switch to Yafray had been removed, but it was present until 2.48, so I back-ported it and I was able to make it work as a plug-in renderer again.
So, what would you like to see? I have no idea what features are broken though because this was the end of the line for Yafray... for whatever reason.

Image-based texture mapping doesn't seem to work. It it has ever worked (I really can't remember) I'll fix it eventually.
Some procedural textures, global illumination and transparency work.

YafRay still exists in the form of YafaRay. Couldn't you use it in conjunction with recent versions of Blender? I can't check right now but there may be an export option for it.

I've tried to make the recent one work but I couldn't. The problem is that it's for a recent version of Blender, but not the latest.
This is a Sauerbraten map. I'm still missing the HDR features because I have to set up an older version of OpenEXR. I'll try it eventually.

Back in the day I used to have it on my Pentium II but I didn't have the resources and the expertise to make anything out of it.
Most importantly, unlike that other thing that renders donuts, this is pleasant to use because don't have to mess around with nodules and testicals.
You want something to be blue or red? You got it. You want sun light and global illumination? There it is.

This seems like a giant waste of time considering you can achieve results like these in realtime now and getting there is also insanely faster now.
I guess it's cool if you're interested in how things worked back then but there are too many people now who think they MUST use outdated software if they want certain results.

It's not a waste of time. I want to preserve the good stuff from before people like you pozzed it with Screen Space GPU gimmicks.
And I wanted to do it before you make it disappear because you're embarassed that something from 23 years ago works better than your modern PBR donut rendering system.

You've yet to prove that from any of your renders.
All I'm seeing is Xbox 360-tier graphics. All you've proven so far is that you're too much of a brainlet to hit F12 in the newer versions.

I just wanted to try... the subject. I haven't done anything special with the materials.
Yafaray on Blender 2.79 it's beyond hopeless because the export plug-in is very broken and I don't think it would be worth the effort to fix it.

These are some random asseticles from:

There are a lot of them, they're free and there would be a whole Python project to be made to make them usable in Blender.
I'll explain later or in another thread maybe but environment pieces like these work similar 9-sector patches.

I also want to make a patch for this Blender 2.49 + Yafray setup so that I have a button that says: "Make the current scene your bitch" and when you press it, it adds a bunch of absurdly colored lights to the scene.

This is just a teaser for:
https://sourceforge.net/projects/su
Yes, it's a rendering system written in Java and it's from 17 years ago. I remember it being quite good but I've never tried the Blender export plugin before.
From what I remember it was supposed to be a Java re-write of PBRT 2 like LuxCore:
https://luxcorerender.org/
Which I'll try eventually. Maybe.
Anonymous at Fri, 26 Jan 2024 16:40:18 UTC No. 971947
Nevermind Sunflow. I just remembered that 10 years ago while trying to make Yafray work (which was what I really wanted but at the time I wasn't as good as programmer to do all the patching and recompiling) I also tried Sunflow and the export plugin. Long story short it needs work and I'm not sure it's worth it.
Yafray on the other hand has that 3DSMAX-ish running on Wicrosoft Windows 95 FF7-ish vibe built-in and none of that very specific "taste" that anything made in Blender seem to have. It feels like a proper expensive cardboard boxed permanently licensed software package. And it's really easy to use. And that's all I really care about.

This is for those who want to "see the wires". Notice the beautiful glPolygonStipple() pattern on the selected triangle and of course, the Nodes editor of Blender 2.49, which I have no idea how to use because I've never used it.

I totally forgot that Yafray had the same option that lets you trade noise for blotches as in Povray.
In the code there seem to be stuff such as a cloud generator, HDRi backgrounds and subsurface scattering.
Unfortunately that functionality is not connected to to the Blender UI at the moment. There is no documentation and the demo files are long lost but one bit at the time I'll try to re-enable it.

I was able to load an HDRi. It seems to work... kinda. But I'm more interested in pic related which should enable this:
https://courses.cs.duke.edu/fall01/
For which I have the internal renderer as a reference for what it should look like. I've also seen something related to a clouds generator and some other procedural texture stuff. Maybe derived from Povray? Subsurface scattering looks like it needs fixing.
>>972672
>Do you have documentation how to use it?
I don't remember any documentation ever existed aside from a file in Blender which is responsible for converting whatever you type into the UI to Yafray commands.

The sky/atmosphere stuff doesn't work in Yafray at the moment. It should be implemented but seems to be disconnected from the interface. Maybe I'll be able to fix it. Pic related is internal renderer with tonemapping.

Initially I meant to post something like this, to showcase the gradient in the sky and because the paper says that this effect should help give a sense of depth to the scene, but then I got carried away.
Anonymous at Sat, 3 Feb 2024 22:31:35 UTC No. 972921
So here's the situation with the atmospheric effect:
Yafray - the implementation is incomplete
Internal on 2.49 - It's sus
Internal on 2.79 - Seems to be closer to what it's supposed to do.
The paper say that the objects in the distance should shift to blue unless in the path of the sun, then the hue should shift to yellow. And I think I can see some of that.

My question is very specific. How do I do this:
https://docs.blender.org/manual/en/
in Blender 3.4.1 which is the one that comes with Debian 12 and which I have?
At the end of the page it says:
"Atmosphere shading currently works incorrectly in reflections and refractions [...] This will be addressed in a later release."
How did they address the issue? By yanking everything out? Do I have to re-create the formulas in the paper with some sort of nodes? If so which ones?

So, first of all I'm not going to be doing any more comparisons after this because I don't have enough patience or CPU power but I've heard of this Spectral rendering thing.
So, I've grabbed this:
https://github.com/mmp/pbrt-v4
compiled it and ran the simplest scene possible: white sky and solid color scenery. In pic related top is Cycles and bottom is PBRT v4. Samest settings as possible. You be the judge but to me... It's pretty brutal.

Just another render with PBRT v4, just because I've made it. I like the sense of depth that it gives. I've read on Povray's manual that when a light ray bounces off a surface it's expected to lose power, but also to lose saturation. PBRT v4 seems to be able to capture this effect.

You are not being honest, you are too invested in difaming yafray, I am starting to think that yafray really touched you, maybe in a metaphorical way? There must be something on your past that is making you act this unhinged way.
Maybe you tried and tried to make it work but you never succeeded? Maybe you were a fan but you lost an important furry render while you were trying to masturbate to homemade furry erotica and you decided that yafray was your enemy? I understand that you never "finish" because the render failed and you never achieved post nut clarity, but you have to learn to let it go.
It's been years, just let it go.

A little test animation rendered by Yafray. I'll do something more elaborate when I'll have time. It does have the feel that I like.

Because of PBRT, I've discovered this;

It should be the same sky model that Unreal Engine uses. I've added to my own little raytracer as a test and I got pic related. Maybe I'll transfer it into Blender later.

I was about to program this myself:
https://github.com/andrewwillmott/s
It generates parametric HDRi which should be usable by any renderer.
I'm still missing the Atmosphere part of this ouside of the internal renderer:
https://docs.blender.org/manual/en/
That's the idea but that manual page is misleading. According to the paper, the effect of the dry atmosphere is not just a blueing of stuff into the distance.

In here >>973215 I think I had the sky sideways. This is what I think the model is supposed to look like.
But now I'm very intrigued by the spectral rendering of PBRT v4 because it should solve the hue change in multiple reflected rays, the dry atmosphere and this >>973220 at once.
It's going to take some work to make up a decent export plugin for it but fortunately I have some old code I've written for PBRT v3. I'll see if I can adapt it or something.
Anonymous at Sun, 11 Feb 2024 01:04:46 UTC No. 973617
Some progress on my own renderer. I've added an approximate way to deal with the sun disk. The problem is that it's a 2 degrees radius circle that carries about half of the energy of the whole sky.
My goal is to eventually have a button that says: "Render this model as if I brought it outside today" with as little other input as possible.
