v0.1.1 in development — expect rough edges
Made in Altushka Builder
No 3D modeling
Assemble from ready-made parts instead of learning Blender. If you can drag and drop, you can build a pet.
Studio-ready MeshParts
Export a single .glb that lands in Roblox Studio as separate, named MeshParts — welded for you by the setup script or the bundled Studio plugin.
84 parts · 6 faces
A growing library streamed from the cloud and cached locally — each face in a stack of colorways (171 variants in all), and new parts arrive without you reinstalling anything.
Bring your own models
Import your own .glb parts and your own face art, and build with them next to the library. Your files stay on your machine — the app never uploads them.
Parts sit flush
Surface snapping, mirroring, and per-axis transform locks are built for one thing: pieces that seat cleanly against each other, not floating almost-right.
Free to use
No login, no paywall — the app and the full asset library, free.
