Thalyn® — Make in Roblox
Build it in Thalyn.
Publish it in Roblox.
Grow a whole world from a single feeling in Thalyn, then carry it into Roblox finished, playable, and unmistakably yours.
Every Roblox world looks like every other Roblox world. Until now.
Build the world once. Take it into Roblox finished.
In Thalyn you pick a feeling, and a whole world grows around it — terrain, trees, water, the light, the weather, all of it. You walk it in first person. You can change its entire look in a single pick. When it feels right, you carry it straight into Roblox.
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 in Roblox, walkable and playable. Sending your world to Roblox costs nothing extra. And it stays yours: yours to publish, yours to keep, yours alone.
Because your world began from your feeling and your choices, no one else lands on the same one. A player knows it's yours the moment they step in — not the terrain they've already seen a hundred times over.
Walk it in Thalyn. 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.
Three steps, start to published.
Grow your world
Pick a feeling. A whole world grows around it. Walk it in first person, reshape it, swap its look until it's the one.
Take it to Roblox
Send it across in a single step, at no extra cost. Terrain, light and atmosphere arrive intact.
Publish and keep it
Open it in Roblox Studio, set it live for players, and it stays yours — to publish, to keep, to build on.
Roblox is where it begins.
Right now, Roblox is where your worlds go to be played. More places to take them may follow in time — but everything here works today.
