I've just opensourced an #OpenUSD FileFormat plugin I had to be able to load USD data from PNG metadata... useful ? dunno... but it's here if you want. Compiled on Windows for usd-25.08 and #houdini 21.0.481 github.com/paoloemiliosel…

Caustics on... with good textures and a broken vase 😅

WORLD-FIRST 🔥 Neytiri is ready to strike in the exclusive first still from #Avatar: Fire And Ash. Zoe Saldaña’s warrior is reeling from the death of her son Neteyam in the threequel. “That pain is seamlessly followed up on,” she tells Empire. “She’s going to question everything.” READ MORE: empireonline.com/movies/news/av…

OpenUSD v25.05 has been released and is now available on GitHub! 🥳 See what's new in the CHANGELOG. github.com/PixarAnimation…

Added a #python editor to my "chaos" app to generate and manipulate #openusd and rendering in #hydra enabled delegates, as usual...

Happy new year! The release candidate for OpenUSD 25.02 is now available on GitHub under the v25.02-rc1 tag. 25.02 is scheduled for release next Tuesday, January 21st. Please check the CHANGELOG to see what's new in this release! github.com/PixarAnimation…

Having fun with #opencv and #openusd

How long would it take me to actually paint all the splats manually ?! eheh... who knows... but it's fun adding instances to a PointInstancer with a "splat" asset-prototype #openusd

Another go at testing #LODs in my #OpenUSD GameEngine SceneIndex #Hydra plugin. This time I used a more realistic usecase, with procedurally generated buildings with each cell having LODs, to allow for a more granular lod-switch for the whole building. youtube.com/watch?v=wp4ktK…

@BeyondDeepSpace Aside of the other standard ones, Storm and Prman

@slider1978 What render delegate are you using?

Removed my custom locators/widgets and just added #ImGuizmo and it's been quite straightforward, nice! Now I can move around those #openusd prims with auto-keyframing for now... youtube.com/watch?v=kWJAco…

@BeyondDeepSpace It's a delegate I wrote for Lighthouse2, a renderer from Jacco Bikker

Back to my standalone #openusd based app, now loading Caldera-set with hero-variants in a CPU based renderer (prman here), looping over all cameras from the set. This is a restructured-version of the original set, to make sure prototypes are shared. youtube.com/watch?v=g1W14D…

Another video about streaming, now between 2 #solaris sessions. Aside from the slow playback on the right (buffering a lot and slow), this shows you that being in #hydra means that the subscriber's #openusd stage doesn't change, as all the edits are just in hydra.

@anderslanglands if by host you mean the publisher, it's zmq with a simple prot-buffer library for encoding/decoding.

@slider1978 What are you using for the wire format between host and subscribers?

I've been asked about this "gameengine" in #hydra and what that means. Not easy via a twitter/x post obviously, but I've prepared a few images to explain it as best as I can here 😅 It's all about #openusd and #hydra being the common languages across hosts/dccs/renders (1)

and you might don't want to stop to one "subscriber", you could have as many as you need for different purposes (live rendering, disk rendering, whatever else) (9 and last, sorry 😅)

Aside of having a fancy demo, this has a lot of possible applications, when you are only interested in the "rendering" of your scene. For example, one host could hold the cost of the usd-stage in memory and another host could render it (without even going through usd-stage (8)
