In this video, Vox’s Phil Edwards interviews Galen Davis of Quixel at Epic Games. His job is as a developer, but sometimes he goes out into the desert to scan rocks.
This scanning economy is a crucial new stage in making realistic 3D games today. Rather than modeling and texturing assets manually, designers often rely on scanned assets to make their games, movies, or other 3d productions look real. Quixel sent Davis to Moab, Utah, just to scan the exotic terrain there for use in Unreal Engine.
There are other ways to get assets for 3D productions, from your phone to the many different available marketplaces. These provide opportunities for photoreal assets to be downloaded instead of created, allowing designers to save time and improve the quality of their work.

Thx for the link.
@@prescriptivereasoning what about colors? also the precision may be an overkill
You should make a video about Blender.
Small correction: at 3:47 the text says The Last of Us: Part II, but it's actually The Last of Us (part 1) being shown
Please make more of this. I love this type of video explaining the methods used for making awesome video games.
Vox: This is a rock.
Me: Dear God.
Vox: But this man is not a geologist.

As a geologist and a gamer, I'm happy to see that rocks are finally getting fair representation in video games. Rocks are not all blob, they have plenty of characters depending on the location. I thank the gaming devs for finally recognize the beauty of rocks.
My friend got all surprised when I played Star Wars: Battlefront for the first time, and started complimenting how great those Tatooine rocks looked.

@@granodiorite9032 haha, btw i am a geologist too.
You guys play no man sky?
Now it all makes sense why 3D rocks in various game-art/digital marketplaces are so expensive
It's the cost of charging the camera
@@robbieaulia6462 its more than the camera. Its also the tent, and also the fuel for the transportation
To me as i once used to develop games in roblox its the texture and the quality of the rock that makes it unique.
@@guardiangusti9808 well its 90 minutes not that long and its not like he goes for 5 hours straight to some location to take pictures because thats a waste of time so ill rather say this people live near to canyons or rocky areas where they take photos
Don't forget those 3D assets produced via photogrammetry always need a 3D modeler to "clean up" the model - fix glitchiness, remove extra geometry, etc. That takes a lot of time and skill to do.
Well, the amount of work that goes into those libraries is, you could say, unreal
Witty
*n* *o* *i* *c* *e*
Well done 👏👏👏👏👏
As a geologist, it's kind of amazing to see other people also find interest in rocks.
Oh man, rocks are some of my favourite subjects to scan! We have Carboniferous Shale in my area and it's just the most fascinating thing, the sheer amount of history behind it boggles the mind.

We video game artists have a whole month dedicated to making rocks everyday!
@Cole Because they have "Unreal Engine" which allows people to create games like Unity
Nah man these guys are just posers, you're the real thing. These video game guys only care about looks, you are into rocks for their personality 😔
Ha! I went to high school with that guy. I had no idea that this is what he was up to these days. Thanks for showing me his commercial, Vox.

They never went to Utah. They actually just 3d scanned a quixel rock inside unreal engine Bc it was easier and we wouldn’t know the difference anyway

I remember just about 10 years ago I did my bachelor's thesis in photogrammetry, I had to literally "stitch" (the more technically correct term is "orient") all of my 100+ photos one by one. And that only gave me a low-poly 3D asset. Now the whole process can be done in less than five buttons. Man, how technology evolves these days!

@@sheeloesreallycool By her stepsister a and now
Vox, please make more of this!
As excited as I am about the prospect of AAA quality assets in indie games and low budget TV shows I'm also worried that over time heavy asset reuse will make games and movies/shows look too similar.
There will only ever be a handful of brick walls in Quixels library.
My hope is that procedural techniques combined with AI will allow artists to create high quality variations of these assets. It might even be possible to do that cat runtime.
But isn't these ment to be starting point for developers. I get what you want to convey, by this not only makes the production cheaper but allows them to focus more time on the actual game then the background. Also they can always build upon the downloaded stuff to differentiate.
@Hay_M Totally! and I mean, even if there was a problem of too few similar models being reused... you can just. scan more rocks. Ymi_Yugy says there's "only so many brick walls in the quixels library" but... we can scan more brick walls. there's more brick walls IRL than anyone would ever need for 3d assets in game development or TV shows
@Hay_M When a documentary on Bethesda showed devs working with assets and taking images from the desert, people assumed the next Elder Scrolls had to be set in Hammerfell, a desert province. But when they showed progress on Starfield, we saw that those same desert assets were had been recoloured and used for the surface of a moon-like planet. It’s mad what artists can do with standard assets.
There are a fair few more than a handful of brick walls on the library already :-)
All in all it's just another brick in the wall.
im liking these videos talking about small things in video games, literally they just take a rock and it has a dozen words about it, i am a small game dev but i dont use 3d engines, i use 2d stuff so its very interesting to take a gander on what you do on 3d engines, also making games even on 2d is hard, so its not that suprising how just a small prop in a 3d game can say a dozen words on how its made, but still its interesting how much a small thing in a game has a bunch of history behind it, literally
edit: theres an account in the replies that has an inappropriate pfp so click the replies at your own risks
you're strangely obsessed with groups of words coming in exact dozens

"to photograph rocks"
Is clearly what I thought, when I got into game design.
modelled my house in the HalfLife engine in 2003. Very quickly found myself photographing bricks and tiles.

Phil Edwards is carrying Vox. Every video he is in is just incredible!
“He has a battery back to keep going longer”
confirmed robots work at epic games
No, a normal map does not tell the renderer how "high or low" parts of the image are. It tells the renderer what the surface normal in different parts of the image is, as the name suggests.
good enough of an explanation for a non-technical audience, normal maps can actually be generated from a height map so there is a relation there.
Most people that might watch this video does not have a clue about 3d softwares or rendering engines. It's easier to explain normals as a somewhat of a bump/height/displ. map.
Or in simpler terms - which way the surface is pointing. This "tricks" the engine during the shading step to add a lot more detail without having to model any more geometry
I came to the comments to find someone who also noticed this, and was not disappointed. Normal and height are two entirely different maps.
I'm so happy Vox is doing these videos on game development, especially the weird stuff no one thinks about, but a lot of effort is put into. Really makes you appreciate the games being made more.
One of the questions we never knew we had and wanted answered
video is borderline misinformation
This video rocks.
🤟🤟🤟
😂😂
😂😂😂
Gold comment❤️😳
"this is a rock"
thank god they explained what that complex item was. I was having a hard time identifying it.
3:30 - The description of a Normal map is incorrect. The colour information describes angles - aka the "Normal" vector of a surface at a given pixel/point. NOT height. Height maps do exist and are referred to as such.
All this effort for a background rock in a video game. Respect!
I didn't know this much work goes into a video game.
It's more than that, that's why video game development is hella expensive.
The idea that literally anyone would go through so much trouble to make a digital rock is almost heart warming lol
3:28 Incorrect. Normal maps contain the normal(which is basically used as curvature info). Height maps contain height info. The names are pretty self-explanatory ^^
the things that go into making a videogame is more complex than i thought
It's amazing how much work is put into this things
And we gamers just walk past these rocks.
Vox: This is a rock
"But its not what you think"

@@kylee.jenner3610 its not a game. It is an experimental test created by epic games to display the capabilities of their new software unreal engine 5

imagine your job being picking cool looking rocks. Pretty cool.
the real benefit of quixel is the consistently high quality , very few other platforms have such quality
Brother bear
I’m in architecture
And you’ve saved my life with quixel bridge when it comes to rendering
Thank you brother bear
Going into this field, I'm so happy to see this concept being given mainstream attention.
Correction: normal map doesnt tell the program how high or low, normal map tells which direction(3d vector) the surface (" the normal") is facing. But it can help with making the surface have depth.
Instead for high low data, there is bump map or depth map.
More videos on game development please!
never knew rocks would become one of the biggest stars in gaming industry
3D Scanning is the future of technology innovated straight from Video Games
The next step is to feed everything to an AI so they can come up with infinite variations.
While it´s not AI, you can make completly random rocks in a software called Houdini. Just enter a different seed and your done. 100% procedual.
Who else loves this video game series 😂😂
1:31 what's the name of this game?
I can't beleive how far we've come that that programs create the rocks, the 'assests', from multiple views.
3:48 this is not TLOU: PART II, it is the first "The Last of Us".
Thank you!
I was going to say that, but didn't wanna sound like a nitpicker
Imagine looking at a rock in a video game and say "hey this rock looks familiar"

Holy cow PLS more video game technology videos🐸🐸🐸
Appreciate the videos on video games development please do more of these!!
I hope more people appreciate VG devs and soundtrack composers
Videos like this are the ones that makes me sit down and ask myself “why am I watching this?”
I hope you guys keep making videogame stuff
definitely loving these videos about video games, keep it up!
Utah has awesome rocks, can't be denied
0:54 That location really sounds like a location from a video game
A video about how shadows work in video games would be really interesting!
3:28 No, you're describing a displacement/bump map. A normal map has data about the angle of the surface.
Interesting I didn't know about this.
Thank you Vox for always educating us. Gonna reach that well deserved 10M soon!

Thank you, VOX for enlighting our minds.
Imagine driving through a rocky desert, and seeing some dudes taking pictures of a rock like it's a historical artifact😂
Those electric trucks being able to be generators mean we get better rocks
Cool
10M soon!
We all know the real way rocks in video games are made is someone downloading a rock from an asset store and resizing them, draging some polygons around and ship it lol
2:49 "Their work saves time for individual Game Designers"
You mean Game Artists. Designers conceive the game mechanics, behavior and design the gameplay space, they usually don't work on visuals. Prop/Environment Artists create the 3D assets and Level Artists use them to dress the levels (broadly speaking).
3:35 "Normal Maps indicate height"
They don't. Height maps represent height, normal maps represent a surface's normal vector (what direction the surface points to). Tbh most game artists don't really get what normal maps actually are, they just know it fakes surface details.
A video on the evolution of cover-based game mechanics would be nice!
strafe left, strafe right. what? there's more?
Might get that from GMTK.
@@GlennDavey - My... What an irresponsibly lazy summation of a gaming mechanic you have there!
Imagine explaining your grandpa that your job is to take photos of a rocks in deserts
Don't wanna be that guy but you kind of got the explanation for normal map wrong. 3:35 Says "color values indicate height". What the color values does it telling from which angle lights hits the surface, helping with the illusion of geometry. A height map on the other hand, would indicate height depending on its values.
"Hurrah Pass..." and the beat drops!
3D is so easy to get into btw! Blender is free to download, I've been playing around with it for months now and it's really fun.
Quixel megascans is awesome!
awesome gig ! gives me motivation !
I'd also like to see how the developers over at DICE did the photogrammetry for the battlefront games cause they looked amazing.
Super useful Vox ! Super useful.
