Building tools
for the
next dimension.
Mixed Reality Creators makes developer tools for Unity and spatial computing — starting with Codex Bridge, an AI pair programmer that lives inside your editor.
Enabling passthrough on your OVRCameraRig component.
enable_meta_xr_passthrough("OVRCameraRig")
✓
Done. Now creating a dark unlit material for the overlay.
create_material("DarkOverlay", shader="Unlit/Color", color="#000000cc")
✓
Passthrough is active and the overlay material is assigned. Want me to add a fade-in animation on scene start?
Codex Bridge,
native inside Unity.
Stop switching context. Codex Bridge puts OpenAI Codex directly inside the Unity Editor — with real awareness of your scene hierarchy, assets, console logs, scripts, and XR project. It's not a generic chatbot. It's a Unity-native AI co-developer.
- Read & write project scripts
- Inspect scene hierarchy & selection
- Create and instantiate prefabs
- Add, remove, and configure components
- Create GameObjects and materials
- Open and save scenes
- Search project assets
- Triage Unity console logs
- Enable Meta XR passthrough
- Discover Meta XR Building Blocks
- Check XR scene setup
- Inspect installed packages
Watch Codex Bridge work
inside your project
From scene assembly to Meta XR passthrough — see how Codex Bridge accelerates your Unity workflow without ever leaving the editor.
AI development,
the Unity way.
In-Editor Chat
A native Codex chat panel inside Unity. Open with Cmd+G and start building — no browser tab, no terminal.
Unity-Aware Tools
Codex can read scenes, create prefabs, add components, triage console logs, and manage assets — all through Unity-native APIs.
Meta XR Ready
Built-in helpers for Meta XR SDK. Enable passthrough on OVRCameraRig, discover Building Blocks, and verify scene setup in a single message.
Spatial ComputingLocal-First & Private
Runs through your local Codex CLI or optional Claude Code CLI. No cloud backend. No data leaves your machine. Auth is handled by each provider's own CLI.
15 Context Modes
Smart Auto Compact bundle by default, plus Selection, Scene, File Tree, Git, Packages, Console — and 6 specialized modes for Build, Addressables, Input, Tests, XR, and ProBuilder.
Saved Chat History
Transcripts saved per project. Reopen any session and resume it on the original Codex thread. Export to Markdown, text, or JSON.
4 Assistant Modes
Switch between Builder, Inspector, Debugger, and Refactor. Each persona tunes Codex's approach to match your current task.
Image Attachments
Paste screenshots from your clipboard or attach files from disk. Show Codex exactly what you see in the Viewport or Inspector.
Give Codex
the right context
Attach live project context to every message automatically. Codex knows your hierarchy, console errors, package versions, and git state — without copy-pasting.
- Auto CompactDefault bundle — version, scenes, console counts, skill state
- NoneClean prompt, no context
- SelectionInspector of selected objects
- Active SceneFull scene hierarchy snapshot
- File TreeProject asset listing
- Project SettingsPlayer, Quality, XR settings
- Git HistoryRecent commit log
- Packagesmanifest.json resolved
- ConsoleRecent log & error output
+ 6 specialized modes: Build Config · Addressables · Input Actions · Test Results · Meta XR Diagnostics · ProBuilder Diagnostics
The right AI
mindset for each task
Each mode shapes how Codex approaches your request. Switch mid-project to match what you're actually doing right now.
Builder
Makes concrete changes. Creates scripts, prefabs, and scene objects when needed.
Inspector
Analyzes first, explains architecture and dependencies before touching anything.
Debugger
Root cause focused. Prioritizes console output and error triage above all else.
Refactor
Improves what exists. Careful, conservative changes with minimal side effects.
Specialized workflows,
not just a chatbot.
Each skill is a purpose-built workflow with its own triggers, required tools, and verification checklist — so Codex Bridge knows exactly how to approach each type of task.
