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.

Viewer Feedback And Status
Triggers
Use this skill for loading state, stream status, connection health, offline, lagged, reconnecting, error banner, warning, toast, status tag, empty state, disabled controls, destructive warning, or operation progress.
Use this with streaming-client, streaming-lifecycle, streaming-messages, stage-management, and viewer-control-patterns.
Feedback Scope
Choose feedback by the scope of the condition:
| Scope | Pattern | Examples |
|---|---|---|
| Workspace/global | Banner or header/footer status | Backend unavailable, auth required, active stream offline. |
| View/panel | Inline alert, placeholder, panel overlay | Stage tree failed, no assets, properties loading. |
| Item | Status tag or row message | Asset missing, prim hidden, upload failed. |
| Transient success | Toast or short-lived status | Settings saved, screenshot captured. |
| Blocking decision | Dialog | Delete, overwrite, reset, discard unsaved edits. |
Assign severity by consequence:
| Severity | Use when |
|---|---|
| Info | Context or neutral state; no action required. |
| Success | Operation completed. |
| Warning | The user can continue, but risk or degraded behavior exists. |
| Error | Something failed or must be corrected. |
Always pair color with text. Color-only status is not sufficient.
Stream Health Model
Use one application-level stream status signal. Components subscribe to it; they do not poll independently.
| State | Meaning | User implication |
|---|---|---|
| Connecting | Session is starting or reconnecting. | Viewport may be blank; commands may queue or no-op. |
| Live | Frames are current and commands can be visually verified. | Normal operation. |
| Lagged | Connection exists but visual feedback is delayed. | Edits may apply before the user can see them. |
| Offline | Stream disconnected or no frames are arriving. | User is working without visual confirmation. |
| Failed | Connection or backend setup failed. | User needs corrective action or diagnostics. |
Suggested placements:
Header or footer: compact persistent status visible from anywhere.
Viewport overlay: local status in the surface affected by stream health.
Panel-level alerts: only when the panel's own data operation failed.
Do not gate every tool panel on stream health. The outliner and inspector can remain useful if their data path is still available. Disable only actions that truly cannot complete.
Loading States
| Situation | Pattern |
|---|---|
| Known progress, such as upload or staged import | Progress bar with label. |
| Unknown duration, such as reconnect or query | Spinner or skeleton in the affected panel. |
| Long renderer/shader warmup | Persistent status text with phase label and logs/diagnostics path when available. |
| Empty data set | Placeholder, not spinner. |
Clear stale content before loading replacement scene data if keeping it visible could mislead the user. For expensive stage reloads, show the previous scene only when the app explicitly labels it as stale or still-active.
Destructive And Blind-Edit Warnings
Classify actions by consequence:
Incremental/reversible: numeric settings, camera changes, selection, AOV changes. Do not interrupt; show status and allow reset/undo where available.
Structural/destructive: delete prim, clear stage, reset settings, overwrite file, discard changes, disconnect active collaboration. Confirm with a dialog.
When stream state is Lagged or Offline, include current status in destructive confirmations so the user understands they may not visually verify the result immediately.
Dialog content should include:
Action name.
Plain-language consequence.
Current stream/session status when relevant.
Cancel action and confirm action.
Destructive styling for irreversible confirm actions.
If a "do not warn again" option is added for degraded stream states, scope it to the current degraded state and clear it when the stream returns to Live.
Disabled State Rules
Disabled controls should have an understandable reason available nearby or on hover/focus.
Prefer keeping controls enabled with recoverable error feedback when a command can be attempted safely.
Never hide a control solely because a backend is temporarily disconnected if hiding it would make recovery harder.
Re-enable controls from a single state transition path; avoid split flags such as
isLoading,isDisabled, andisOfflinefighting each other.
Validation
Before finishing UI status work, test:
Initial no-stage state.
Connecting, Live, Lagged/Offline, and Failed stream/session states where supported.
Stage-load progress and stage-load failure.
Selection cleared and selected-object invalid after scene switch.
Destructive confirmation with normal and degraded stream status.
Narrow viewport layout with status text visible and not overlapping controls.

Requirements and compatibility
Written for: OpenAI Codex
Works with: Claude Code, Claude apps, OpenAI Codex, GitHub Copilot, Cursor, Gemini CLI, Kiro, OpenCode, Goose, Amp, Roo Code, JetBrains Junie, Factory Droid, Devin (ex-Windsurf), Mistral Vibe, OpenHands, Letta
“Works with” means the tool reads the open Agent Skills format; a skill written for one tool may use features others lack.
The author says: Orchestrator skill. Downstream focused references may require NVIDIA GPUs, ovrtx, ovstream, ovui, OpenUSD, Python, Node/React, Tauri, Electron, C++, or cloud GPU deployment access depending on the selected viewer path.
