AI-powered 3D scene assembly from natural language using OpenUSD
Project description
🐦 Meet BowerBot
In the rainforests of Australia and New Guinea lives one of nature's most remarkable architects: the bowerbird.
Instead of relying on appearance, the bowerbird collects, curates, and arranges objects from its environment into a carefully constructed 3D composition. Every object is chosen. Every placement is intentional.
BowerBot brings that same idea to OpenUSD.
BowerBot is an AI agent for OpenUSD, a conversational interface that helps any team using OpenUSD go from an empty scene to a production-ready stage by:
- finding assets from any connected source (Sketchfab, local disk, company DAM, or any custom provider)
- placing them with spatial awareness
- authoring materials inline in ASWF-compliant asset folders
- setting up native USD lighting (sun, dome, point, area, disk, tube)
- validating technical correctness (units, hierarchy, references, bindings)
- packaging the result for any USD-compatible runtime
🎯 What BowerBot Is (and Is Not)
BowerBot is:
- A USD authoring agent for any OpenUSD pipeline: VFX, AEC, simulation, spatial computing, digital twins, robotics, e-commerce 3D
- A conversational interface for the full authoring surface: assets, lighting, materials, validation, packaging
- A fast way to go from 0 → production-ready scene
- A pipeline assistant that handles technical correctness (units, hierarchy, references, bindings)
- A pipeline guardian that catches asset issues before they reach production
- Extensible by design: new asset sources, DCCs, and domains plug in as skills
BowerBot is NOT:
- A final scene generator
- A replacement for DCC tools like Maya or Omniverse
- A system that produces perfect composition or artistic layouts
Scenes generated by BowerBot are meant to be opened, reviewed, and refined in your DCC.
Think of it as:
"Block out the scene instantly, then refine like a pro."
Pipeline Quality Built In
BowerBot enforces ASWF USD standards at every step, not just placing assets. Fixable mismatches (non-canonical folder names, external dependencies) are auto-normalized on intake so the project copy is always self-contained. Production-required invariants are validated at intake too: assets with non-identity root transforms (Maya pivot dance, unfrozen DCC exports) are refused with a clear message and the option to bake transforms into vertex data on the project copy without touching the source. Unfixable violations (wrong root prim type, missing defaultPrim, incorrect metersPerUnit, circular references, missing dependencies) are caught at assembly time with a clear message about what's wrong and how to fix it.
"The cheapest bug to fix is the one you catch before it enters the pipeline."
✨ What It Does
Watch BowerBot build real scenes end-to-end on the demo playlist on YouTube. Each video walks through a project across asset discovery, placement, materials, lighting, validation, and packaging.
Open the resulting .usda in Maya, usdview, Omniverse, Isaac Sim, or any USD-compatible tool to refine composition, lighting, materials, or downstream pipeline steps.
Projects are persistent. Close the session, come back later, and continue where you left off.
✨ Features
- 📦 OpenUSD native: references,
defaultPrim,metersPerUnit,upAxis, all correct out of the box - 🏗️ ASWF-compliant asset folders: geometry, materials, and lighting split into a root + layer files, per the USD Working Group guidelines
- 🧳 Self-contained intake: non-canonical source folders are detected via USD composition, canonicalized (
root.usd→<folder>.usda), and external dependencies (textures, sublayers) are localized into the asset folder so the project copy is always portable - 🎨 Material binding: apply MaterialX or existing
.usdamaterials to specific mesh parts - 💡 Native USD lighting: sun, dome, point, area, disk, and tube lights at scene or asset level
- 🧩 Automatic unit handling: assets in cm, mm, or inches are scaled correctly at reference time
- 📐 Geometry-aware placement: bounding-box resolved positions for surface, above, below, or nested placements
- 🔌 Pluggable skills: connect any asset source (Sketchfab, PolyHaven, company DAM, or build your own)
- 🧠 Multi-LLM support: OpenAI, Anthropic, and any provider via litellm
- 📁 Project-based workflow: one folder per scene, resumable across sessions
- ✅ Scene validation:
defaultPrim, units, up-axis, reference resolution, and material binding checks - 📦 USDZ packaging: export for Apple Vision Pro, Omniverse, or any USD viewer
- 🏗️ Onboarding wizard: zero-config setup in 60 seconds
Built on OpenUSD, the ASWF USD Working Group standards, and the Alliance for OpenUSD (AOUSD) core spec driven by Pixar, Apple, NVIDIA, and others.
🚀 Quick Start
Install
There are two paths for end users (pick whichever fits your environment), plus a separate path for contributors who want to modify BowerBot itself.
End users, Option A: uv (recommended)
uv manages Python and isolated tool environments for you, so you do not need to install or pin Python yourself.
uv tool install bowerbot
End users, Option B: pip
If you already maintain a Python 3.12+ environment, plain pip works:
pip install bowerbot
Contributors: developer install
To modify BowerBot itself, clone the repo and let uv manage the dev environment:
git clone https://github.com/binary-core-llc/bowerbot.git
cd bowerbot
uv sync
uv run bowerbot onboard
First-time setup
bowerbot onboard
The wizard asks for your LLM API key, your asset library directory, and your projects directory, then writes ~/.bowerbot/config.json. One file, one place, no .env.
Create a project and start building
bowerbot new "Coffee Shop"
bowerbot open coffee_shop
To plug in asset providers like Sketchfab, see Skills below.

📁 Projects
Each project is a self-contained folder with metadata, scene, assets, and packaged output in one place:
scenes/coffee_shop/
project.json # Metadata: name, created_at, updated_at, scene_file
scene.usda # The USD stage (references only, clean and readable)
scene.usdz # Packaged output (Apple Vision Pro, Omniverse, etc.)
assets/ # ASWF folders + self-contained USDZs used by this scene
textures/ # Scene-level textures (HDRI maps for DomeLights, etc.)
Projects are resumable. Close the session, come back later, and continue where you left off:
$ bowerbot open coffee_shop
# Project: Coffee Shop
# Scene: scene.usda (5 object(s))
You: Show me the scene structure
BowerBot: Scene has 5 objects...
You: Remove Table_03
BowerBot: Removed /Scene/Furniture/Table_03
🔄 How It Works
BowerBot is conversational: you tell it what you want and it uses the right tools to build your scene. Behind the scenes, it manages asset discovery, USD composition, materials, lighting, and more.
Asset Discovery
BowerBot searches for assets across all connected sources, prioritizing what's already available:
-
Local assets first: BowerBot checks your local asset directory (
assets_dirin config.json) for USD files (.usd,.usda,.usdc,.usdz). This includes anything you've exported from Maya, Houdini, Blender, or any DCC tool, as well as assets previously downloaded from cloud providers. -
Cloud providers if needed: If the asset isn't found locally, BowerBot searches connected providers (any installed skill, e.g. Sketchfab) and downloads the asset to your local directory.
-
All downloads are cached locally: Once an asset is downloaded from any source, it lives in your
assets_dirand is available for all future projects without re-downloading.
Scene Assembly
When you ask BowerBot to place an asset, it routes by what the source looks like and always produces a self-contained ASWF folder in the project:
- Folder with a detectable root (canonical
wall/wall.usda, or non-canonicalwall/root.usd+wall/geo.usd+wall/mtl.usd): the root is identified via USD composition (the file no sibling depends on), the folder is copied into the project, the root is canonicalized to<folder>.usda, sibling references are rewritten, and any externally-referenced textures or layers are localized into the folder so the output is portable. - Loose USD geometry (
.usd,.usda,.usdcfrom your DCC exports): wrapped in a fresh ASWF folder named after the file stem, producing<stem>/<stem>.usda+geo.usda. - USDZ files (from Sketchfab, DAMs, etc.): placed as-is since they're already self-contained.
When an asset can't be safely intaken (missing external dependencies, or a folder with multiple independent USDs and no clear root), BowerBot refuses with a message naming the conflict instead of guessing.
Material Workflow
When you apply materials to an asset, BowerBot writes them into the asset folder's mtl.usda, not the scene file. The scene stays clean with only references:
You: Apply wood material to the table top
BowerBot: [searches local assets for "wood" materials]
[discovers mesh parts: table top, legs, frame]
[writes material definition + binding into assets/table/mtl.usda]
Bound /table/mtl/wood_varnished to table top
The result is a production-ready asset folder:
assets/single_table/
single_table.usda <- root (references geo + mtl)
geo.usda <- geometry (untouched from source)
mtl.usda <- materials inline + bindings
Scene Output
The scene file (scene.usda) contains only references and lights: no material data, no geometry copies, no sublayers. Clean and readable:
def Xform "Scene" (kind = "assembly") {
def Xform "Furniture" {
def Xform "Table_01" {
xformOp:translate = (5, 0, 4)
xformOp:scale = (0.01, 0.01, 0.01)
def Xform "asset" (
references = @assets/single_table/single_table.usda@
) { }
}
}
def Xform "Lighting" {
def DistantLight "Sun_01" { ... }
def DomeLight "Environment_01" { ... }
}
}
Open it in Maya, usdview, Omniverse, Isaac Sim, or any USD-compatible tool to refine.
🔌 Skills
Skills extend BowerBot with external asset providers, DCC connectors, and simulation runtimes. Each skill is a separate Python package, discovered at runtime through Python entry points (bowerbot.skills). The skill SDK lives in bowerbot.skills; skills themselves ship and version on their own.

Community skills
Built by external contributors, published to PyPI under each author's namespace, and listed here for discoverability. To add yours, open a PR on this README adding a row to the table below. The skill must be open source, installable via pip from public PyPI, and follow the contract in CONTRIBUTING.md.
| Skill | Author | Install | What it does |
|---|---|---|---|
| be the first |
When this list grows large enough to warrant tooling, it becomes the BowerHub skill registry.
Installing a skill
Three steps. Sketchfab as the worked example.
1. Install the skill alongside BowerBot. With uv, add it to the same tool environment:
uv tool install bowerbot --with bowerbot-skill-sketchfab
To add more skills later, rerun with every --with you want and --reinstall:
uv tool install bowerbot --with bowerbot-skill-sketchfab --with bowerbot-skill-polyhaven --reinstall
If you used plain pip to install BowerBot, install the skill in the same Python environment:
pip install bowerbot-skill-sketchfab
2. Get any credentials the skill needs. Sketchfab requires an API token from https://sketchfab.com/settings/password. Each skill's README documents what credentials (if any) it needs.
3. Add the skill's config block to ~/.bowerbot/config.json:
"skills": {
"sketchfab": {
"enabled": true,
"config": { "token": "your-sketchfab-token" }
}
}
That's it. BowerBot auto-discovers the skill via Python entry points the next time you run it. The exact shape of config is per-skill; consult the skill's README.
Verifying a skill is installed
Three commands, in increasing depth. All work on Windows, macOS, and Linux.
1. Ask BowerBot what it sees:
bowerbot skills
Lists the core scene-builder tools plus every extension skill the registry has loaded successfully. If your skill shows under "Extension skills" with its tools, you are done.
2. If it does not appear, check the package is installed:
pip show bowerbot-skill-sketchfab
If the package is installed, this prints its name, version, and location. If not, it prints Package(s) not found and exits non-zero. Install it (see Installing a skill above). Replace bowerbot-skill-sketchfab with whichever skill you are checking.
3. If the package is installed but BowerBot still does not see it, inspect the entry-point registration directly:
python -c "from importlib.metadata import entry_points; print('\n'.join(f'{ep.name} -> {ep.value}' for ep in entry_points(group='bowerbot.skills')))"
If your skill does not appear in this output despite being pip-installed, the skill's pyproject.toml is missing or broken. File an issue on the skill's repo. If the skill does appear here but bowerbot skills still does not show it, the gap is in your ~/.bowerbot/config.json: the skill's block is missing, enabled: false, or the credentials fail validate_config().
Private and in-house skills
Skills do not have to be public. Install from a private PyPI index, a git URL, or a local path:
# Private PyPI
pip install bowerbot-skill-acme --index-url https://pypi.acme.internal/
# Direct git URL (any host)
pip install git+ssh://git@github.com/acme/bowerbot-skill-acme.git
# Local path during development
pip install -e /path/to/skill
Entry-point discovery works the same in all three cases.
Trust
A skill's SKILL.md is injected into the LLM's system prompt, and its tools run with the same access as core tools. Only install skills you trust. Open-source skills are auditable; closed-source skills should come from a vendor you have a relationship with. The first-party table above is the only set Binary Core has audited end-to-end.
⚙️ Configuration
All settings live in ~/.bowerbot/config.json. The skills block holds the config for any skill packages you've installed; the example below shows what it looks like once you've installed bowerbot-skill-sketchfab (see Skills). A fresh install starts with "skills": {}.
{
"llm": {
"model": "gpt-4.1",
"api_key": "sk-...",
"temperature": 0.1,
"max_tokens": 4096,
"context_window": null,
"summarization_threshold": 0.75,
"num_retries": 3,
"request_timeout": 120.0,
"max_tool_rounds": 25
},
"scene_defaults": {
"meters_per_unit": 1.0,
"up_axis": "Y",
"default_room_bounds": [10.0, 3.0, 8.0]
},
"skills": {
"sketchfab": {
"enabled": true,
"config": { "token": "your-sketchfab-token" }
}
},
"assets_dir": "./assets",
"projects_dir": "./scenes"
}
Switch models by changing one line:
{ "model": "gpt-4.1" }
{ "model": "anthropic/claude-sonnet-4-6" }
{ "model": "deepseek/deepseek-chat" }
Tested Models
| Model | Tool Calling | Instruction Following | Recommended |
|---|---|---|---|
gpt-4.1 |
Excellent | Excellent | Yes (default) |
gpt-4.1-mini |
Good | Good | Yes (budget) |
gpt-4o |
Poor | Poor | No (skips tool calls, ignores SKILL.md) |
anthropic/claude-sonnet-4-6 |
Excellent | Excellent | Yes |
BowerBot relies heavily on tool calling and SKILL.md instructions. Models that don't follow tool-calling patterns reliably will produce poor results.
Token Management
BowerBot automatically manages conversation context to stay within model limits. Two settings control this:
| Setting | Default | Description |
|---|---|---|
context_window |
null |
Context window size in tokens. null = auto-detect from the model. |
summarization_threshold |
0.75 |
Fraction of context budget that triggers history summarization. |
Additional tuning options (usually don't need changing):
| Setting | Default | Description |
|---|---|---|
tool_result_age_threshold |
2 |
User turns before old tool results are compressed. |
min_keep_recent |
6 |
Minimum recent messages always kept verbatim. |
summary_max_tokens |
512 |
Max tokens for the summarization LLM call. |
Tool-Calling Loop
BowerBot runs a loop where the LLM requests tool calls, BowerBot executes them, and the results are fed back. Complex requests (e.g. binding materials to many mesh parts at once) can require many rounds.
| Setting | Default | Description |
|---|---|---|
max_tool_rounds |
25 |
Maximum LLM ↔ tool exchange rounds per request. Increase if BowerBot stops with "Reached maximum tool-calling rounds" on legitimate workflows. |
Error Recovery
BowerBot automatically handles transient API errors:
| Setting | Default | Description |
|---|---|---|
num_retries |
3 |
Retries for rate limits and transient errors (429, 500, 503). |
request_timeout |
120.0 |
Seconds before a request times out. |
- Rate limits and transient errors are retried automatically with exponential backoff.
- Validation errors are fed back to the LLM so it can auto-fix issues and re-validate.
- Permanent errors (bad API key, unknown model) show a clear message without crashing.
🏗️ Architecture
BowerBot is organized FastAPI-style:
- schemas/ describe data (pydantic models + enums)
- utils/ are pure-function primitives (no
SceneState, no orchestration) - services/ are state-aware orchestrators, one function per tool, signature
(state, params), calls utils and other services freely, raises on errors - tools/ are the LLM-facing surface, thin adapters that guard preconditions, call ONE service, wrap the result in
ToolResult
Adding a feature is the same three-file change every time: schema, service, tool.

Design principles
- One tools module, one service: every service module backs exactly one tool surface, with one orchestrator per tool. Shared primitives live in
utils/, called freely by any service. - Functions only in tools / services / utils: classes live in
schemas/(pydantic models, enums) and a small set of state objects (SceneState,Project). - Tools are thin: guard preconditions, call ONE service, wrap in
ToolResult. No business logic, no util calls, no cross-service routing. - Services own orchestration: take
(state, params), do the cross-service and multi-util work, mutate state, raise on errors. - Utils are pure primitives: no
SceneState, no other services. Composable building blocks. - State lives in one place:
SceneStateholds the open stage, the project binding, the asset library path, and the object counter; tool handlers thread it into service calls. - All
pxris inservices/andutils/: the rest of the codebase never importspxrdirectly. - Prompts are content: editable
.mdfiles, not Python constants. - Skills are external integrations: new asset providers ship as Python packages discovered via entry points.
- One config file:
~/.bowerbot/config.json, no.env.
📐 USD Compliance
Every scene follows OpenUSD best practices and the ASWF asset structure guidelines:
Scene level
metersPerUnit = 1.0,upAxis = "Y",defaultPrimalways set- Standard hierarchy:
/Scene/Architecture,/Scene/Furniture,/Scene/Products,/Scene/Lighting,/Scene/Props - References only: no inline geometry, no scattered material sublayers
- Wrapper-prim pattern isolates scene-level transforms from asset-internal ones, so DCC export transforms (Maya pivots, rotations) stay untouched
- Pre-packaging validator checks
defaultPrim, units, up-axis, reference resolution, and material bindings
Asset level
- References (not sublayers) per ASWF guidelines, for predictable opinion strength
- Materials inline in
mtl.usda, lights inline inlgt.usda, nested references incontents.usda - Automatic
metersPerUnitconversion across composition boundaries - Identity root transforms enforced on intake: pivot dances, baked rotations, and other unfrozen DCC export ops are rejected (or baked into vertex data with explicit user consent), so nested placements compose predictably
- Nested placements mirror the scene-level wrapper convention (a wrapper
Xformholds the per-instance transform, an inner/assetchild holds the reference arc), andmove_asset/remove_primon a nested path route writes tocontents.usdainstead of authoring per-instance overrides at scene level
🗺️ Roadmap
What's next for BowerBot. Contributions welcome:
- USD Variant Sets: ASWF-compliant variants on asset root prims (materials, geometry, lighting, configurations, and more)
- Scene templates: JSON-driven scene assembly with asset resolution
- DCC exporter: Maya/Houdini tool to export scene layout as BowerBot JSON
- More asset providers: Fab, PolyHaven, Objaverse, CGTrader skills
- MCP Gateway: FastAPI server for web UI and external AI clients
- Web UI: chat panel + live 3D viewport
- BowerHub: community skill registry
🤝 Contributing
BowerBot is open source and welcomes contributions. The best way to start is writing a new skill for an asset provider, DCC, or simulation runtime you use. Skills ship as separate pip packages discovered through the bowerbot.skills entry-point group.
Read CONTRIBUTING.md for the skill contract, the required FastAPI internal layout, and a worked pyproject.toml example for a stand-alone skill package.
For a complete reference, see bowerbot-skill-sketchfab: a real first-party skill on PyPI, with the production layout, entry-point registration, validation, and release pipeline you can mirror for your own.
