The best USD explanation I've seen. Thanks for breaking it down.
Aw shucks. Thank you for the compliment. It's my pleasure. = )
@@Autodesk_Maya I agree. Good explanation.
Whare yoooouuu doing here!
Great stuff! Love to see more coming.
Loved the explanation ! great video , also very nice to finally see your face :) …. Thank you 😊
Good someone is covering this, interesting to see a timeline on the actual creation and release of the kitchen though - I definitely maybe saw it first two years ago, at least.
You're right! USD as a concept (and even as a resource) has been around for a while now. But it's taken a while for the industry (both production and tools) to understand and see the benefit of adopting it into their pipelines. It takes a while to design and build the things needed to support USD, and what we're seeing now is a maturation of those designs into actual usable things that can be practically implemented to make production better.
Animal Logic (the makers of the Lego Movie, amongst others) and Nvidia are good examples of this adoption trend. It's only going to spread more from here.
This has been really helpful to start to address why I can't get my cross app files to work. Thank you for the simplicity
The legendary auto-genius; so good to finally put a face on all that great wisdom, awesome
Finally~ a face reveal! Now to the matter at hand, as a 3D artist (who worked in a small studio that receives outsourced works from such big studios), we've encountered USD but we never knew what they are. We called them stand-ins or blocked scenes (as in basic blocking). We, the 3D BG generalists would work on a single asset and then it was up to the lookdev to do the final compositing (both in maya & final renders). So had no idea about this, but it took me 6 years to know thanks to you! :D
How do you guys market yourself to bigger studios?
Great explanation. Thank you very much!!!!
Thanks for the vid! Perfect timing
Hey man, really useful video. thanks
It's the hierarchy of decision-making, and how to rein that in to an achievable goal, which is being addressed here. This is a result of too many individuals making decisions, and their indecisiveness, or misdirection, which trips up productions, usually resulting in everyone blaming the artists. If you're a designer in a too-many-chefs scenario, here's a system which ranks those decision makers and assigns them to tiers ... which is how they are arranged anyway, only now it's embedded in the format, enforcing the discipline and driving decisions to cut costs and improve efficiency.
freaking awesome thank you!!, love the fact that you tried to keep it DCC agnostic
Thanks You! Please more USD videos in the future :)
Great presentation! :)
Nice explanation!
Great vid, thanks
wow it's very very nice to see the face of my best teacher in the whole world!! thanks so much for showing your face.
Amazing!
finaly face revealed
Man you are my super hero, you helped me a lot during my career, thank you.
So glad to be of service!
May you make a video and discuss the shading process regarding usd pipeline. For example, how to use it among Arnold, redshirt and other third-party renders. how to create the assets being able to export and import or only even being able to apply shaders on it.
As a Blender user, I can't be more excited to know that USD is a thing in Blender now, such a powerful format so everything can be connected :D
It might be integrated more than in Maya.
2:19 . Ha yes, Maya preventing me to install a zip bomb
Thank you so much, very helpful video as always !
few images of primitives without antialiasing looks clumsily😬, but the idea of usd is now clear!
good overview. thanks!
I can’t wait to see what you have next regarding usd. I’m really interested in how USD is used for animation. Most demos and talks seem to be based on static scenes.
I concur. Would love to learn more about animation in the USD world.
Thank you, very infermative.
THANKYOU FOR MAKING THIS! MORE USD CONTENT PLEASE!!!
I would love somthing that would cover materials & Textures in USD.
And Exporting Animation with USD.
I've got you covered for animation at least. = ) ruclips.net/video/XW9Pu2ep-kM/видео.html
Yeah how the textures work would be awesome. I keep getting my scenes showing up all white in other apps
Finally a face reveal ! Oh yes finaly !! For me the best ever as maya teacher. Love u Matt ! Thanks a lot for all your tuts. The Maya magician !!!! great voice, best tutorials. Again thanks
Aw shucks, thank you! I'm glad to help!
I totally understand why they call the layers opinions, but I hope people realise they are more flexible than that. You can have multiple lighting setups for your own shot, object placements etc that you can quickly switch between.
This was so great an in depth. Thank you. Currently im trying to understand usd workflow between maya and unreal as iv never used usd stage actor and iv tried to bring in a camera track in unreal and it hasnt worked for me yet. Was told it's too complicated and more for production workflow. Any advice?
Unfortunately I'm not too familiar with Unreal's support for USD right now, so it's hard for me to answer. I believe your colleagues are right though - USD isn't highly supported in games at the moment. Of course this could change in the future.
Hi Matte, I 'm looking for information about ACI Autodesk certified Instructor. Where can I take the exam in order to be certified ?
Sound quality could be better. The "p"s especially in PPPPrim is a bit odd.
模型转成usd后，自动软边是什么原因 啊
so i won't be scared if I don't have nanite in Maya, just in ue5?
How do you get these folder structure in the outliner? When I Create > Universal Scene Description > Stage from File it shows as a single object in the outliner. Thanks!
Did you make sure to turn on Shapes? I recommend checking out this video for the full Maya workflow: ruclips.net/video/-vs5YFxWTdw/видео.html
I haven't touched maya in years (I've transitioned more to 2d and stop mo) but this is amazing! I wish my laptop could still run maya like it used to. I'll have to get back into maya and blender when i finally get a new computer (:0
new versions of maya are faster. I have an old machine , and few years a go I wasn't using it for 3d because it was very slow. But now I'm surprised it is not that obselete as I thought.
@@angosalvo5734 Ohhh... in that case i may jump back in; thanks for the tip!
I like the teapots.
haha, I miss in-person Siggraph
@@Autodesk_Maya Needs the Stanford Bunny to complete the ensemble.
Technically, It is a more and more improved version of the Maya's reference data, Same idea but in a modern way.
it’s soooooooo much more than that though….
USD, Universal, only if it can export useful information.
Which it can't do well enough.
Any luck with imageplanes?
I downloaded the file and imprted it, but it doesnt show the usd structure, just a normal Maya one. The Mya USD plugin is loaded, so is there a different setting or another plugin I need?
When importing USD assets you'll need to go to Create > Universal Scene Description > Stage from File. This is because you don't "import" USD data in the traditional sense. I'll have a video up on this topic soon!
@@Autodesk_Maya The whole scene is closed, there's no subfolders etc..
I'm still unclear how rigging would fit into this, do we ref a usd model? Can we swap lods and opinions live in the rig and animation? etc. thanks
Everyone works as always, but in the end you export your stuff - models (usd type), animation (usd cache), simulation (usd cache ), etc - to usd hierarchy tree (same as outliner in maya) and this usd tree can be opened and viewed in all software that supports usd. The whole team exports their stuff to the same usd tree.
To expand on uzi zizu's answer a bit: USD actually typically does not even include the rigging. Typically a mesh is animated like normal in Maya, then the resulting skin is output to USD.
USD is extensible and a DCC maker like Maya or a studio could design their own extension to store riggging data in USD. In USD jargon, they call this a custom schema.
Of course, the value of such an extension is proportional to its valid design, felxibility but more importantly adoption.
Thank you for all the replies! Makes sense kind of like an abc then. I think many td's would still appreciate an in-depth video on this topic! Ty
hello bro, may i know where are you from?
FACE REVEALLLLLL!!!
One question: How does it comapare to the traditional referencing system in Maya besides peformance? I'm trying to convince my coworkers to swtich to USD but couldn't find a better reason.
It's really quite different. Interoperability with other software and studios supporting USD is a big part of it. Also the whole idea of layers and opinions isn't something that's really possible with referencing.
✨👌😎🙂😎👍✨
I have to be honest - the name alone scares me. (USD)
why i dont have the option to edit usd by rightclicking on it?
Do you have the newest version of the USD plugin installed?
@@Autodesk_Maya yes i do.dowloaded it from github.
@@mosy252 And you're attempting to edit a polygon object?
@@Autodesk_Maya yes.when i right click on the usd object .i dont have the edit as maya data option.
@@mosy252 Hmm, very strange. I would try posting about it in the GitHub forum to have a developer look at that then.
A great explanation and a good job, but many complex/complicated sentences that cost me much time to understand😭😭😭😭I think your papers are high-levels😂😂
But you didn't explained how a 3DsMax user sees this.
For solo projects. Can you use USD to bypass exporting let's say a Maya file to an FBX just so it could work on Blender? So instead of converting mb files to fbx, I could just save it as a USD file and it'll work with Blender out of the box?
Yes, you can definitely do this
how to rig with usd ? @Autodesk_Maya
