The Most Valuable File Format You've Never Heard Of

Creating a functional 3d tools pipeline that interfaces with multiple kinds of software can be an absolute drag due to data incompatibilities. Thankfully, Pixar has saved the day with their new open source standard for 3d data formatting, OpenUSD! Today we'll talk about what USD is, the problems it solves, and how it can help you and your tools pipelines.

The song used in the outro got copyright claimed so I had to trim it out hence why the audio is worse now. But no one watches outros anyways it's 2024.

I got covid at siggraph so unfortunately I didn't have much time to create a cooler demo for you all making use of USD, but I hope you all like it! Be sure to speak up about a Godot integration if that interests you. Next video I'll be back on my goat stuff.

It's better than perfect, it's standardized!

[opalpersonal]

"there were 17 formats."
someone: "we should make a new, universal format that can use everything."
"there were 18 forma-- oh wait, people are actually using it universally? well damn."

Transitioning to an ad with the cat on the side, is one heck of a technique for an engagement trap

Apple embracing PIXAR's creation as a standard is surprising, until you remember it's PIXAR. You tried, Apple.

I feel like this is, if anything, underselling what USD can do. From USD files potentially being human readable and editable, to the ability to use hydra to plug a USD scene directly into most render engines, to the ability to layer USD scenes across multiple files, editable across multiple users and different software in parallel, it is an absolute beast. And that's just the benefits I've noticed as an artist with zero pipeline or coding experience.

It was a magical moment the first time someone opened a USD ascii file in front of me and created a basic PBR material by just typing the values into notepad.

Alan Wake 2 (well NorthLight) used USD files for their entire game. It allowed them to do live editing from Maya, to the editor, to the game. They put out a few videos when Alan Wake 2 launched about the new features to their engine

"If it finishes before you die then it's fine"
Is a mantra fitting for Python programming

[HarbAlarm]

watching this as someone who makes vrc assets
wait why aren't we using .usd everywhere?
"usd currently cannot describe rigs"
..ah that's why

I fucking love it when he goes "But Acerola..!"

[Epsilous]

I'm not a 3D dev, but seeing open-source standardization like this is really exciting. Much love to the talented people working to make development more accessible, universal, and user-friendly!

The strategy to keep us entertained on the sponsor segment with your cat worked on me, get your free ad money

[TarcisMoreda]

uhm ackshually 🤓 the api is in c++ with python bindings

[JamesR]

0:50 _gasp_ Apple and Nvidia working *together* on something?!?!

[apolo]

7:20 A small correction: right-handed and left-handed coordinates are actually the opposite of what's shown in this video. Handedness isn't about what axis points up but about the relationship between the axes.

[Ryhon]

GLTF came out 8 years ago and we thought it would be the universal standard. Pixar released USD and seemingly everyone jumped on the hype train and forgot about GLTF and now there's 2 competing standards

[rismosch]

7:14 correction: in a z-up right handed coordinate system, y points away from the viewer. take your right hand, point your thumb (x) to the right and your pointer finger (y) away from you, and you'll see that your middle finger (z) points up. In Unitys left handed y up coordinate system, z points away from the viewer.

4:30 having a cat video play during a sponsor segment is so effective. NighHawkInLight also does something similar (plays with his parrot)

[DarkPortall]

0:14 he says unify yet shows an intersection. who are you, really, acerola?

[leotaku]

14:48 Interesting, I remember you talking about Godot not really having the support for the graphics-heavy stuff you want to do a while back. Has something changed in that regard?
