Hi all,

We’re Plattipus Research and Production Lab. Inspired by the new UsdVolParticleField3DGaussianSplat schema introduced in OpenUSD v26.03, we built Houdini Solaris integration — and we’re open-sourcing it today.

https://github.com/plattipus/houdini-gsplat [github.com]

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.
