Hi all, We’re Plattipus Research and Production Lab. Inspired by the new `UsdVolParticleField3DGaussianSplat` schema introduced in OpenUSD[](https://aousd.org/blog/openusd-v26-03/)v26.03, we built Houdini Solaris integration — and we’re open-sourcing it today. **→ [https://github.com/plattipus/houdini-gsplat](https://github.com/plattipus/houdini-gsplat)** It implements the v26.03 schema natively inside Houdini 21 Solaris: a custom Hydra delegate, UsdImaging adapter, and three LOP nodes: PLY Import, Gsplat Instancer, and Uruk. Import a `.ply`, see it live in the viewport, instance it across a scene at O(M+N) memory, all without leaving the LOP network. ![gs-splat-instancer](https://us1.discourse-cdn.com/flex016/uploads/aousd/original/2X/9/94966ba2cb7d5550abd449c91d105bb705391fb0.gif) Thanks, -– Plattipus ---

This is great to see! I’ll share with Lee as well, but it’s awesome to see the adoption
