Thalyn® — Make in Roblox
Build it in Thalyn.
Take it to your people.
Say how it should feel — out loud, typed, or picked — and walk the world Thalyn forms around it. Then take it into Roblox, finished and playable, for the people you made it for.
“Every world I make looks like everyone else's.”
Yours from the first stepMost generators hand you their world. Thalyn builds one around yours.
Drop in your own model — a castle, a cottage, a ruin, a monument — and Thalyn treats it as the reason the world exists. Terrain, sightlines and paths arrange themselves so it sits where it should and stays reachable on foot.
Then walk the finished world, open the style selector and choose a different visual character. Every surface, texture and material transforms at once — in real time, while you're standing in it. Not a filter over the top. The whole world. Your feeling, your centrepiece, your look: nobody else lands on the same place.
The first comment on your next place: “wait — how did you make this?”
Then hand it to the people you made it for.
When it feels right, the whole world goes into Roblox — terrain, assets, lighting and atmosphere intact, with triangle budgets enforced so it runs properly on the devices your players actually use.
Nothing flattens on the way over. The hills you climbed, the light at the hour you chose, the fog resting in the valley — all of it arrives walkable and playable. A starter game pack is included in every export, so there's something to do the moment your friends walk in.
Exporting is free and unlimited. It's a pipeline step, not a generation. And what lands in Roblox is yours — yours to publish, yours to keep.
A world only you have walked is just a place. Export is how it becomes somewhere.
You walk it in Thalyn. Your players walk the same world in Roblox.
Everything you built and everything you felt comes with it.
Terrain
The full landscape — slopes, water and surface materials — walkable from one edge to the other.
The placed world
Trees, rocks, structures and foliage, sitting at the scale and angle the world asked for.
Light
The hour you chose and the mood of its light, carried over exactly as you left it.
Atmosphere
Sky, fog and weather, so it feels in Roblox the way it felt under your feet in Thalyn.
Solid ground
Terrain and major features keep their collision, so players really walk, climb and explore.
Your look
Change the world's entire look in one pick — that whole character travels with it.
Your world gets recognised as yours before anyone reads the name.
Three steps, start to published.
Inside Thalyn it's three moves: Say how it should feel. Place what you love. Walk in. Here's how that world reaches your players.
Make it yours
Say how it should feel, and a whole world forms around it. Put your own model at the heart of it, walk it in first person, and swap its look until it's the one.
Take it across
Send it to Roblox in a single step, at no extra cost. Terrain, light and atmosphere arrive intact.
Open the doors
Open it in Roblox Studio and set it live for players. It stays yours — yours to publish, yours to keep.
You've walked it alone since you built it. Step three is the day somebody else walks it too.
Roblox is where it begins.
Right now, Roblox is where your worlds go to be played — and where the people you want to show them to already are. Universal glTF export ships today too, for Blender, Godot and anything else that reads it. More places to take them may follow in time; everything here works today.
