Added some features to the https://t.co/w5bNEEpFvi #openusd #hydra render delegate, and I thought... what if... it runs a simple stable diffusion model at the end of the progressions directly in usdview ? 😅

and having some fun with lens flares... too much? ^_^

I decided to experiment with Gemini CLI and see how far it would go. I'm making an #openusd Hydra delegate with a pathtracer integrated, without touching any line of code. It's been an experience so far... not super straight forward but it's working.

somehow, these renders of the Intel MooreLane asset in hdGemini with the denoiser, look like paintings 😅

[Paolo Selva @slider1978]

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

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.”

Having fun with #opencv and #openusd

[Paolo Selva @slider1978]

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

[Paolo Selva @slider1978]

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.

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

[Paolo Selva @slider1978]

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...

[Paolo Selva @slider1978]

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

[Paolo Selva @slider1978]

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.

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.

[Paolo Selva @slider1978]

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

[Paolo Selva @slider1978]

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)
