realitykit-rendering-materials

realitykit-rendering-materials is a skill for Codex from tomkrikorian/visionOSAgents. It costs 102 tokens per session (1,128 once invoked), scanned A, original, MIT.

A guide for building and troubleshooting how RealityKit scenes look on visionOS, including meshes, materials, cameras, lights, shadows, and visual effects. RealityKit is Apple's framework for creating interactive 3D scenes.

In plain words
What is it for?
Use it to display models, assign materials, configure cameras and lights, tune shadows and effects, work with Gaussian splats or decals, and manage features such as level of detail or occlusion.
Why use it?
It helps identify whether a problem is caused by scene content, lighting, materials, rendering settings, or performance controls. It also points specialized shader and USD work to the appropriate guide.

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.

Security

Grade A, and why

realitykit-rendering-materials 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.

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

RealityKit Rendering Materials

Quick Start

  1. Confirm the issue is visual: mesh display, material assignment, camera projection, lighting, shadows, post-processing, splats, decals, LOD, occlusion, or probes.
  2. Load the narrowest rendering reference that matches the feature.
  3. Route ShaderGraph or USDA material graph editing to shadergraph-editor.
  4. Route local USD stage rendering through realitykit-visionos-developer; route USD authoring to usd-editor.
  5. Validate on device or simulator with concrete visual checks, because many rendering issues are asset-, lighting-, or hardware-dependent.

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.
