Minecraft EXTREME GRAPHICS: RAY TRACING IS FINALLY HERE! [umsoea]

They probably used 1spp path tracing then blurrs it without leaking off the polygons to denoise it. Then they used it as a lightmap casted in real time on the textures...

@John Theux not sure what any of that means lol but you've given me a good place to start searching :)
Thx

Cant wait until gpu's are powerful enough to do this in real time on other games

@John Doe Oh, you can see at that it's a "fake lightmap" that's created. I mean that the "lightmap" is directly on the screen and not on the polygons so it can't be saved and you need to make a new render each second, it's a temporal filter that merged several frames together to denoise them https://www.youtube.com/watch?v=7MV26bOSAyk&t=320s

@John Theux thanks! Very helpful :)

Maybe :D

T M did u survive?

rip graphics card

My PC was launched in space

It's called default improved with pbr.

@umsoea thanks a lot, gotta say it looks quite good

@Asier Ochoa wow, someone that knows what PBR is in a Minecraft video...
the Minecraft community really is surprising me in a good way. ^w^

and this does seem to be pretty PBR. it even has Fresnel.

@Spirit Wolf I wish the minecraft community were a bit more "invested" in videogame graphics terms too. I have seen people ask how people using ptgi have implemented Nvidia rtx in Minecraft lmao.

@Asier Ochoa well PBR is a general term! X3
I had to study it for doing CGI :P
but yeah, PBR is great.

Yeah, but it would be nice if in version 7 or 8 of sonic ether's ptgi shaders that he added realistic shining to the water.I

Also, umsoea doesnt develop these shaders

My fan overclocks from just from watching any of the videos. It's also quite hot, and I have to pause the video every 20 seconds and wait for it to cool down. Somehow my i pad has no issues watching the videos, which surprises me because its quite old and cheap.

Mehdi Noori I can’t tell if that’s a joke or actually real cause why would ur computer fan go up by a yt video

xaxa yes

Ok

@demomanfromtf2 no u

What the fack @demomanfromtf2

5:20 the different depths of the " shade " freaking awesome

hey! You uploaded this famous graphics video 3 years ago!

@Radioaktiver Müll Haha, let me tell you a secret: This is my new channel :)

@WurmiSaft ooooooo

Rtx 2060 can easily run this

batlefild v is optimised for low end PCs so it runs well on basicly every computer

@Cubic Ralsei then let it be rendered!

Not true "ray tracing reflect all" would mean no computer in the world could compute it. More correctly: Ray Tracing reflect what the game Engine tells it to reflect.
Ex: battlefield removed ray tracing for GRASS because it was seen as a useless performance hit.

But that'll make my computer explode

he's a vampire

Moustache Pikachu I pay $10 a month on the patreon for this

Watch sonic ethers video. He explains how he gets rid of a lot of the artifacting. Also Minecraft is not a game with complex shapes, e.g. most things in Minecraft are 6 face blocks, whereas battlefield has millions of triangles at every angle on just one object, it's a lot more complex.

Works with non RTX Cards.

But rtx carda are faster than gtx cards

@Spexta HD ironically not with this shader... yet

He have a GTX970

Raytracing is not new, it works on older graphics cards too, Nvidia simply made it easier by adding RT cores on the new generation graphics card

@Pedro Miranda but why developers add rt in games after the release of rtx model ?

@Budget Gamer because now the graphics card will be able to run it more easily, which means that the developers will need to spend less money and time optimizing it. But who am I to say.

@Pedro Miranda yeah , AMD GCN cores also fully capable of RT once they applied to their driver update .

You don't need rt cores to do ray tracing, RT is done in movies from 2006 an up, and they use CPU power. the RT cores are like an ASIC device, It makes those RT calculations way way faster than normal mainstream hardware.
Heck i think there was a demo of ray tracing back in the 80s.


This is why GPUs have mainstream cores, ROPs (raster operations pipeline) and TMUs (Texture mapping unit). Think of the RT cores and the AI cores are like ROPs and TMUs. Dedicated hardware for a very specific task. Also the dedicated x264 controller for video encoding and decoding (this is why we can record 4k 60fps on the GPU and not lose any performance in fps)

@Quetzalcoalt ohhh thank you

Make sure you had rtx card

Its not its as damanging as any other game

No, you can use any card but maybe rtx performs better, I don't know exactly.

Cody stated several times he's not using RTX cores for his shaders (which are unavailable in any case in minecraft)
So you should be able to use ptgi e4 with any card

Nvidia made it confusing but they don't have a monopoly on raytracing. This technique is decades old, they just have cards now tailored to this form of rendering technique.

@Andrew Doiron I think it will sadly not work well with amd cards, because they don't do well with opengl geometry shader, wich are most likelu used there.

@Stéphane du Hamel you may be right, I don't know much there.

lmao this is not ray tracing this is the shader mod an rtx card wont help at all because its not ray tracing

@CaptainCrazy500 It is ray tracing, just not DXR.

@CaptainCrazy500 this is in fact raytracing. Everything shown in this video from the physically accurate lighting to the non-screen space reflections demonstrates this. And if that's not proof enough, Cody himself has explained the techniques being used here.

@Stéphane du Hamel OpenGL shouldn't be a problem though, quite the contrary.

@Andrew Doiron I wouldn't say they made it confusing, although I do see plenty of confused people. I'd say it's just the new term Nvidia so quickly associated with their brand.
And technically, this is new technology in the way it is being applied.
Yes, raytracing exist from decades and it has been used in real-time before, but today there are new and better ways to implement it, aided by more powerful hardware.

@umsoea from what I could gather, the RTX cards seem to actually be unoptimized for the task they have been designed for.
I heard some say they were rushed into production, although, probably, some of the issues they seem to be having will be fixed through software updates. so I don't know how much they would perform better, then again, they do have more power.

@CaptainCrazy500 it is indeed pathtracing. Nvidia didn't invent it and you don't need any special gpu for it.

@Andrew Doiron No, it's path-tracing, look on the developers patreon. Also look at a video on the difference between the two :)

"Overcome" from the youtube audio library

@umsoea thank!

What if I told you raytracing and even pathtracing exists for years and runs on nearly any graphics card. And what if I told you nvidia's rtx is mostly marketing.

@umsoea i wouldnt believe you because that simply isnt true... try to run the new quake rtx remake with a gtx card and all the textures and lighting is messed up

@Kalle Well, maybe you are right :) So many years I believed a lie.

@Kalle RTX was designed to do more with ray-tracing and improve it's overall performance, not introduce it, ray-tracing has been around since the 90's, Nvidia made the RTX series to help do it in real-time. And this shader-pack isn't ray-tracing it's path-tracing, look up a video on the two.

Check out @tuxedolabs on twitter. Another person proving that ray-tracing is possible without rtx. Dennis does it using OpenGL and I assume Sonic Ether is doing the same, although Dennis has resorted to using voxel space due to its much better preformance. I wonder what his approach to getting it running this well is. Either way, it's hella impressive.

@OllAxe this shaderpack uses pathtracing not raytracing btw

@umsoea RTX is not supported on Open gl

@Kalle  Nvidia didn't invent ray-tracing. They only invented hardware that is designed to do ray-tracing in real-time and an SDK to take advantage of that hardware. Software raytracing has been around for decades. Path-tracing is an application of ray-tracing which shoots rays to simulate real-life light. Path-tracing is used when rendering 3D-movies and is why pre-rendered 3D graphics can achieve photorealism. This tech has traditionally been to slow to use in video games, so game developers have had to resort to using cheat-methods to achieve realistic lighting and reflections in games, but that's changing.

Both software and hardware ray-tracing are getting fast enough to implement path-tracing in games. Sonic Ether and Dennis Gustafsson both use software-based ray-tracing to path-trace lighting in their games/shaders, while Battlefield V and Metro Exodus take advantage of the RT cores of RTX cards to do the same thing.
