Isaac Sim extension

The Rigyd SimReady Importer is an NVIDIA Isaac Sim / Omniverse Kit extension (rigyd.simready) that brings the Rigyd conversion pipeline into the simulator. Convert any 3D model, text prompt, or image into a physics-enabled SimReady USD asset and reference it straight onto your stage — no manual download or drag.

Note

Rigyd emits native SimReady USD (Z-up, metersPerUnit=1.0, with mass / center-of-mass / inertia / friction / restitution), so the extension is a thin API client and stage loader, not a format converter.

Install

1. Clone the extension repo.

2. In Isaac Sim: Window → Extensions → ☰ → Settings → + (Extension Search Paths) and add the absolute path to the repo’s exts/ folder.

3. Find rigyd.simready in the extension list and enable it (toggle Autoload to keep it on).

4. Open Window → Rigyd, paste your rgyd_live_… API key, Save key, then Test connection.

Tip

Mint the key at app.rigyd.com (Settings → API Keys). It spends your account’s credits, just like the API and CLI.

Use

Flow	Input	Cost
Text → SimReady	a prompt	2 credits
3D file → SimReady	.glb/.gltf/.fbx/.obj/.stl/.ply/.usd* (+ optional target triangle count)	1 credit
Image → SimReady	1–4 images	3 credits

The panel submits the job to api.rigyd.com, polls to completion (same lifecycle as the API), downloads the self-contained format=usd result ZIP, unzips it, and references the .usd under /World. Press Play to simulate.

Status

v1.0.0 — validated end-to-end on NVIDIA Isaac Sim (textures + SimReady physics intact). All three input flows (Text / Images / 3D file) are implemented.
