What should we do?
Studio + Open Cloud
Work directly in your game.
Build
Create instances, scripts, and UI. Upload meshes and set up products through Open Cloud.
Check
Run tests, review 3D work, capture Studio, and inspect errors.
API + SDK
Read scenes, run test sessions, and follow logs from your own TypeScript scripts.
Player data
Read specific saved fields through Open Cloud. No writes to player data.
UI → code
Export Studio UI as React Luau or plain Luau. Layout and appearance, not behavior.
Project preferences
Respect mapped source files. Remember materials, colors, and stud surfaces.
Playtests
Start play or multiplayer sessions, track their status, and read new output.
Profiling
Inspect CPU/GPU frame times and slow frames. LibMP setup required.
