Use when importing or wiring assets in Lens Studio via MCP — textures (PNG), 3D models (FBX/GLB), materials and their texture slots, PBR base/normal slots, duplicating/moving assets, and pulling private files off Google Drive into the project.
Use when writing custom shaders in Lens Studio via MCP — Custom Code (GLSL-like) graph nodes, port declarations, surface/system inputs, animating without a Time node, masking faces, and script-settable graph parameters. Includes why graph wiring is GUI-only.
Use when a Lens / Spectacles lens talks to an external backend via InternetModule.fetch — the Preview is device-only and throws synchronously, `Request` isn't a runtime constructor, and microphone + network APIs are mutually exclusive. Includes the companion-app pattern for voice without an on-device mic.
Use when running, previewing, and verifying a Lens Studio project edited over MCP — applying scene edits to the running lens, screenshotting the preview, checking that TypeScript compiled, and working around log/compile timeouts. Includes the "no Save tool" reality.
Use when building spatial UI in Lens Studio via MCP — cards, buttons, text, icons, images. Covers text sizing, the whitespace-background trap, plane orientation, readable labels, textured/rounded image planes, and renderOrder layering.
Use when editing a Lens Studio scene through the MCP server — setting properties, wiring component/asset references, attaching scripts, or navigating the scene graph. Covers the component-by-component rule, the reference "{}" echo, and script attachment.
Use when making Lens Studio objects respond to Spectacles hands (pinch/poke/tap) via the Spectacles Interaction Kit — adding Collider + Interactable in code, wiring events, hover/press feedback, and a screen-navigation state machine. Includes the "enable the SIK root" gotcha.
