No. Every kit works fully with no AI installed. ArTchie AI is the one kit that talks to an agent, and it routes to a service you already have — Unity AI Assistant, Claude Code, Grok Build, or any signed-in CLI agent you add. Nothing is bundled and nothing bills through us; it runs on your own account and credits.

Unity 6.0 LTS (6000.0) or newer. The suite is built and exported from 6000.0.81f1 and verified on 6.3 and 6.5 — see the matrix below. Alpha and beta editors are not supported targets.

Any render pipeline. The editor kits don't touch rendering at all. The included demo scene and its settings target URP, so if you open the demo in an HDRP project the demo materials will need the usual conversion — your own scenes are unaffected.

Everything is under Assets/ArTchie Studios/: the nine kits in ArTchie Tools/, the demo, the showcase loaders and your scripts beside them. Nothing is installed into Packages/ and nothing points outside your project. Full C# source, no DLL-only code.

In the built game. BedderScript ships runtime code: the VM, the in-game IDE (F1), the block face (F2), and the scene editor (F3) all run inside your player. The other eight kits are editor-only and never ship in a build.

A .bedder script runs in a bytecode VM with no reflection, no filesystem and no network access. Every frame has an instruction and memory budget. The only things a script can call are the builtins on the published census — anything not on it does not exist. Read Security & the sandbox for the full model, including the wider trust tier that scene mods sit in.

Yes — the save is the mod. Save as… snapshots the scripts it uses into the save and offers Share it now…, which writes one .abspack file. Open ▾ → Open from file… installs one, and on Windows double-clicking an .abspack opens the game with it. The moddable-root pattern covers offering modding without making the whole game moddable.

Expected on first run. Atlas needs one Rebuild Index pass before its graph is populated; after that it refreshes itself while the editor is open. Atlas indexes Assets/.

No, and it says so. It is an experimental translator assistant that makes mistakes. Everything it cannot map is left as a comment tagged TODO(bs) for a human to finish. Treat its output as a first draft.

Static meshes with materials and diffuse textures. Rigs and animation are not imported. Model formats and the allow-list are in the manual.

Three places: the Getting Started window that opens on first load; Tools › ArTchie › ★ Documentation at the top of the menu and first inside every kit's submenu; and this site, which is generated from the same files. Edit › Preferences › ArTchie chooses whether docs open in Folio or your external app.

Yes. Full C# source ships, every kit is namespaced, and it's all project assets in your Assets/ folder. Change what you need. The one thing to keep in mind: if you edit a kit, your changes and a future update will need merging by hand, the same as any source you own.

Purchases go through the Unity Asset Store, so its refund policy and the standard Asset Store EULA apply. For anything the store can't resolve, write to us.
