Altushka Builder v1.2.2
Build Roblox pets in minutes
Snap modular parts together, paint it, add an effect, and export straight into Studio as separate, named MeshParts. No 3D modeling.
No account macOS: signed & notarized macOS & Windows 100 parts · 6 faces · 160 effects
v1.2.2 in development — expect rough edges
One unbroken take — pick a body, snap on ears and a tail, drop a face, export. No cuts, no speed-up.
Made in the app
Every one of these is a real export
Why Altushka
Built for people who don't want to open Blender
Six things the app does so you don't have to. No modeling, no UV unwrapping, and no rigging for a static welded pet.
Paint it, don't just build it
Paint straight onto the pet in 3D, then make it Golden, Diamond or a colour you pick. Put a particle effect on any part and watch it play. It all travels into Studio with the 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.
100 parts · 6 faces · 160 effects
A growing library streamed from the cloud and cached locally — each face in a stack of colorways (171 variants in all), and new parts, faces and effects 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.
Yours to sell
No login, no account. Publish and monetize what you build inside your own Roblox games — the license on the parts you export is perpetual and royalty-free.
Who it's for
You don't need to be an artist
Four ways in — and the last one is why the app exists.
Game devs
You're shipping a pet system and need twenty creatures that look like a set — not twenty commissions and three art styles.
Sim & UGC builders
You need volume. Eggs, rarities, tiers — and every pet has to import the same predictable way, every time.
Solo creators
You can script and you can build. Modeling has always been the wall. This removes the wall, not the ambition.
Never opened Blender
You've made nothing in 3D and you're not sure you're allowed to start. You are. This is the door.
Shipping in the open
Still being built
v1.2.2 shipped September 21, 2026. Every release, every dead end, written up as it happens.
Two paint fixes
1.2.2 is out with two fixes to paint mode.
ReadEffects, and finishes
1.2.1 is out: particle effects on any part, and Golden, Diamond or your own colour over a painted pet.
ReadThree copies, three different wraps
Each copy of a part can wear its own UV wrap now, not just each kind.
ReadBefore you download
The five things people ask first
What does Altushka Builder cost?
Whatever the itch.io page says at the moment you download it — that page is the only place a price lives, so it is always the current one. There is no account to create either way.
Do I need to know 3D modeling?
No. You assemble creatures from ready-made modular parts — no Blender, no sculpting, no rigging. If you can drag, drop, and snap pieces together, you can build.
How does it work with Roblox?
You export your finished creature as a .glb plus a small setup script. Import the .glb into Roblox Studio, then either click Assemble Pet in the bundled companion plugin or paste the setup script into the command bar — your pet is assembled for you, welded together, with its face applied.
Can I sell what I make with it?
Yes. You own how you arrange and build the parts, and you can publish and monetize your creations on Roblox — within Roblox's own rules and our Terms. The one line not to cross: don't resell the raw parts, or a bare export, as a standalone asset for others to reuse.
Do I need to be online?
You need internet to grab the catalog and download each part, face and effect the first time you use it. After that they are cached locally so you can keep building.
