What is shadergraph-editor?

A guide for creating and troubleshooting Shader Graph materials in Reality Composer Pro, Apple’s visual tool for making 3D assets and materials for RealityKit.

Use it to choose shader nodes, expose values for runtime control, load or update ShaderGraph materials, inspect exports, or build graphs programmatically in Swift on visionOS 27.

It helps connect visual shader graphs with runtime Swift code and diagnose problems when materials are exported through USD or MaterialX.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.00820
Opus 5.5	$0.00024	$0.00328
Sonnet 5.5	$0.00012	$0.00164
Haiku 4.5	$0.00006	$0.00082

Security

Grade A, and why

shadergraph-editor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ShaderGraph Editor

Quick Start

Default to Reality Composer Pro. Use raw USD or MaterialX inspection only when debugging exports or interoperability.

Decide whether the task is node selection, runtime parameter control, export debugging, or sample selection.
Identify whether the material is authored in Reality Composer Pro, loaded from USD / .reality, intentionally created from MaterialX data, or built programmatically with the visionOS 27 ShaderGraph API.
Load only the matching reference files.
Route text-level USD structure edits to usd-editor.

Load References When

Reference	When to Use
`references/shadergraph-node-reference.md`	When choosing RealityKit Shader Graph nodes by category.
`references/runtime-api.md`	When loading `ShaderGraphMaterial`, working with promoted inputs, or updating parameters at runtime.
`references/programmatic-shader-graphs.md`	When building shader graphs in Swift with the `ShaderGraph` API (new in visionOS 27), `ShaderGraphMaterial.Program`, `PortalMaterial.Program`, `LightingModel`, or PBR subsurface scattering.
`references/export-debug.md`	When inspecting exported USD or MaterialX, or when a graph fails to load or render as expected.
`references/samples.md`	When selecting the closest repo sample before authoring a new effect from scratch.
`references/apple-material-boundaries.md`	When deciding whether to author in Reality Composer Pro, load a `ShaderGraphMaterial`, or debug named material/resource failures.

Workflow

Start from the closest existing sample when possible.
Author or refine the graph in Reality Composer Pro.
Promote the inputs that need runtime control.
Load entire authored entities with RealityKit entity-loading APIs, or load a standalone material with ShaderGraphMaterial only when the app needs the material itself.
Match material prim paths, file names, bundle names, and promoted parameter names exactly.
Load and update the material through the runtime API.
Inspect exports only when the normal authoring path stops explaining the failure.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
