AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
The Omniverse Realtime Viewer skill acts as a central orchestrator for developing USD-based viewer applications. It provides a structured approach to selecting implementation recipes, enforcing architectural conventions, and managing dependencies. By utilizing a set of focused reference documents, it guides developers through the lifecycle of building, configuring, and validating viewer applications, ensuring consistent behavior across different delivery paths such as local workstations or streaming environments.
What it does
- Routes development requests to specific implementation recipes based on the target delivery path.
- Enforces architectural rules for USD rendering, stage management, and UI integration.
- Provides guidance on camera selection, input handling, and viewport interaction.
- Standardizes the integration of AOV switching and render product configuration.
- Facilitates the capture of validation evidence for viewer readiness.
- Maintains separation between user-provided USD files and application-specific session state.
When to use it
- When initiating the development of a new USD viewer application within the Omniverse ecosystem.
- When determining the appropriate delivery path for a viewer, such as local native or streaming.
- When needing to implement consistent camera, selection, or UI behavior across viewer projects.
- When integrating advanced rendering features like AOV switching into an existing viewer.
Advantages
- Ensures architectural consistency across diverse viewer implementations.
- Provides a clear, modular path for adding specific capabilities like input routing or data display.
- Promotes clean separation of concerns between stage data and viewer-owned state.
- Standardizes the validation process for consistent delivery.
Usage examples
- “I need to build a browser-based viewer for USD files.”
- The agent will route you to the streaming viewer recipe, providing guidance on WebRTC stream setup, UI integration, and viewport interaction.
- “How do I implement AOV switching in my local USD viewer?”
- The agent will provide the AOV switching reference, detailing how to map render vars and update the display state on the server.

Omniverse Realtime Viewer
This is the top-level entry point for the Omniverse Realtime Viewer skill package. It is self-contained: all required routing, conventions, and validation guidance live in the selected references.
Use the focused reference documents as implementation recipes. This file chooses the right recipes and preserves the architectural rules that must hold across all generated viewer apps.
Instructions
Start by classifying the requested viewer, then read only the references needed
for that delivery path and feature set. Implement the render path first, layer
interaction and UI behavior on top of it, and finish by capturing validation
evidence from references/validation.md.
Read Order
Read
references/routing.mdto choose the delivery path and focused references.Read
references/conventions.mdbefore implementing camera, input, selection, viewport, streaming protocol, scene loading, or environment behavior.For broad viewer requests, read
references/usd-viewer-app/README.md.If the delivery path is unclear, read
references/streaming-vs-local/README.md.If the prompt includes layout, panels, controls, inspectors, status, or UX, read
references/viewer-ux-workflow/README.mdand then the focused viewer UI references. This applies to React/WebRTC, Tauri, Electron,ovui,ovwidgets, and Dear ImGui apps; "frontend" means user-facing UI, not only browser UI.For viewport interaction, read
references/viewer-input-routing/README.mdbeforereferences/camera-controls/README.md,references/native-picking-selection/README.md, orreferences/object-selection/README.md.Read only the focused capability references needed for the requested app.
Use
references/validation.mdto capture review evidence before handoff.
Non-Negotiables
Use
ovrtxfor all USD and 3D rendering.Browser apps display an
ovstreamWebRTC video stream plus UI. The browser does not render USD geometry.Do not substitute WebGL, Three.js, Babylon.js, PlayCanvas, A-Frame, model-viewer, react-three-fiber, glTF browser viewers, or other client-side 3D renderers.
If local validation cannot run because the GPU/runtime environment is absent, scaffold the
ovrtxpath and document the runtime requirement. Do not add a browser-renderer fallback.Keep user USD files unmodified. Viewer cameras, render products, render vars, settings, selection metadata, and runtime state belong in session/composite layers or app state.
Keep one owner for
renderer.step(), stage mutation, native picking, selection writes, and live attribute writes.Keep dependency acquisition in
references/dependencies/README.mdand deployment choices inreferences/cloud-deployment/README.md; do not duplicate package locations or deployment setup.

Build Workflow
Classify the prompt by delivery path, target user, required capabilities, runtime environment, validation needs, and explicit constraints.
Select a small reference set. Start with the recipe or routing reference, then add focused capabilities such as camera, picking, hierarchy, properties, render settings, transform tools, cloud assets, or deployment.
Read selected references before writing app code. Follow their build order, import order, data-channel contracts, and renderer ownership rules.
Implement the core render path first, then input routing and camera, then selection and data panels, then scene/settings features, then packaging or deployment.
Treat the selected references as the behavior contract for API shape, compatibility, and generated project structure.
Capture validation evidence before calling the viewer ready.
Examples
For a browser viewer request, use the streaming recipe references plus camera, picking, hierarchy, properties, render settings, and stream-status references.
For a local workstation viewer request, use the local or native delivery references plus renderer setup, stage loading, viewport input, and validation.
Completion Checklist
Selected references match the user's intent and delivery path.
No code path uses a browser-side 3D renderer for USD.
The generated app has one clear owner for render stepping and stage mutation.
User USD files remain untouched by viewer-owned session data.
Camera, input, selection, scene loading, and stream behavior follow
references/conventions.md.Setup/build/run results and visual interaction evidence are captured with
references/validation.md.

Environment And Validation
Environment Variable Summary
Set before any ovrtx work:
export OVRTX_SKIP_USD_CHECK=1Set when renderer plugins or MDL libraries do not resolve:
export OVRTX_BIN_PATH="$(python3 -c 'import ovrtx, os; print(os.path.join(os.path.dirname(ovrtx.__file__), "bin"))')"
export LD_LIBRARY_PATH="$OVRTX_BIN_PATH/plugins${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}"Use nvidia-runtime.md for current NVIDIA runtime acquisition
locations. Do not keep separate ovstream source URLs or cache controls here.
Set only when an ovstream install cannot locate SDK libraries automatically:
export OVSTREAM_LIB_PATH=/absolute/path/to/ovstream/native/libsSet for local UI under a known display:
export DISPLAY=${DISPLAY:-:0}Set when the default home cache is not writable:
export XDG_CACHE_HOME="$PWD/.cache"
export CUDA_CACHE_PATH="$PWD/.cache/cuda"
export __GL_SHADER_DISK_CACHE_PATH="$PWD/.cache/gl"
export npm_config_cache="$PWD/.cache/npm"Verification Checklist
Run these checks after installation:
Confirm GPU and driver are visible with
nvidia-smi.Confirm Python is the expected interpreter inside the virtual environment.
Confirm
OVRTX_SKIP_USD_CHECK=1is set before renderer imports.Confirm
ovrtximports and renderer construction succeeds on the target GPU.Confirm
OVRTX_BIN_PATHresolves to the installed ovrtxbindirectory when plugin resolution fails.Confirm
pxrimports only in the selected query subprocess.Confirm
usd-coreis exactly24.11.Confirm
ovstream.initialize()andovstream.shutdown()work for streaming Omniverse Realtime Viewers.Confirm
warpcan see CUDA devices when using CUDA conversion paths.Confirm
@nvidia/ov-web-rtcappears innpm lswhen building a browser streaming frontend.If the app imports local viewer UI components, confirm
frontend/src/viewer-ui/exists and exports the referenced components andViewerBackendtypes.Confirm
omni.uiimports only when building a local desktop Omniverse Realtime Viewer with prebuilt local UI packages.Confirm
.cache/is writable when running in containers, CI, or shared environments.
For generated browser-streamed viewers, add these readiness checks before reporting completion:
Start the Python server from the generated run wrapper or equivalent command.
Wait for
/healthzto return200 ok; if it does not, capture the server log.Confirm the log contains a first-frame message after render-var mapping and RGBA-to-BGRA conversion.
Run the frontend build and browser smoke check only after the server runtime proof above has passed or has produced a concrete failure report.
Failure Mode Index
Wrong Python package index:
ovrtxinstall fails or pulls nothing. Use NVIDIA PyPI forovrtx; use PyPI fornumpy,warp-lang, andusd-core==24.11.Incorrect ovstream acquisition: use the current PyPI package source in
nvidia-runtime.md.Platform mismatch: wheel is unavailable or native import fails. Confirm OS, architecture, Python version, GPU driver, and package wheel tags.
Import order issue: USD registry,
_tf, duplicate debug symbol, or MDL resolver errors. SetOVRTX_SKIP_USD_CHECK, constructovrtx.Rendererfirst, and isolatepxrin a subprocess.Native library path issue:
CRenderApi, MDL, ovstream native, or plugin load failures. SetOVRTX_BIN_PATH, dynamic library path, orOVSTREAM_LIB_PATHas appropriate.GPU access issue: renderer or streaming initialization fails despite successful imports. Verify
nvidia-smi, container GPU devices, driver support, RTX cores, and NVENC.Display issue: local desktop UI cannot open a window. Verify
DISPLAYand X server availability.Cache permission issue: Warp, CUDA shader caching, GL shader caching, or npm fails under
~/.cache. Set project-local cache paths and ignore.cache/.Frontend registry issue: npm cannot resolve the NVIDIA package. Check package spelling, the
@nvidiaregistry in.npmrc, lockfile, and proxy configuration.Local viewer UI issue: TypeScript cannot resolve
ViewerBackend,StageTree,Inspector, or related local viewer UI imports. Generatefrontend/src/viewer-ui/fromviewer-backend-interface, or update imports to the app's actual local module path.
