Questions and answers
The basics on what Altushka Builder is and how it fits into a Roblox workflow.
Is Altushka Builder free?
Yes — free to download and use, with no account and no paywall on the core builder. The asset library is free too. If paid asset packs ever arrive, the builder itself stays free, and we'd tell you first.
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, each part a separate, named MeshPart, welded together, with its face applied. From there you color it and script it like any model.
Can my pet have a face?
Yes. Pick from 6 built-in faces, each in a range of colorways (171 variants in all), choose which side it goes on, and it travels with the export into Roblox Studio automatically. You can also import your own face art and use it the same way.
Can I use my own 3D models?
Yes. Import your own .glb models into a personal library and build with them right next to the official parts — they place, snap, mirror, and export exactly the same way. Your models stay on your machine; the app never uploads them anywhere.
Can I recolor or paint parts?
Parts ship in neutral tones, and there are two paths. The quick one: recolor the MeshParts in Roblox Studio after importing. The deeper one: paint directly onto a part's texture in any image editor — the app gives you the part's texture layout, and your painted version travels with the export into Roblox.
Can I keep editing a pet later?
Yes, two ways. Every export saves a .altushka preset alongside the .glb — open it in the Builder to pick up exactly where you left off. And if all you have is the Roblox side, export the model from Roblox Studio and import that file straight back into the Builder.
Can I sell what I make with it?
Yes. You own how you arrange and build the parts, and you can use and sell your creations inside your own games and experiences — publish and monetize on Roblox freely. The one line not to cross: don't resell the raw parts, or a bare export, as a standalone asset for others to reuse. The full rules are in our Terms of Service. Credit isn't required — but it's appreciated: a line like "pets made thanks to Altushka Builder" in your game description always makes our day.
What do I need to run it?
A Mac on macOS 12 or newer (Apple Silicon or Intel), or a 64-bit Windows 10/11 PC. Both versions are on the download page.
Do I need to be online?
You need internet to grab the catalog and download each part the first time you use it. After that, parts are cached locally so you can keep building, though we can't promise uninterrupted offline use.
How do updates work?
The app checks for new versions and shows a banner when one is out — no background installer. You grab the new build from the download page whenever you're ready.
