Hi all,
We recently released TerrainSuite, a free Studio plugin for generating biome terrain — realistic or blocky — right in the editor.
Get it: https://create.roblox.com/store/asset/117295054452350/Biome-Terrain-Generator-TerrainSuite
What it does
-
Fresh Generate — pick a biome preset (Alpine Valley, Moon Craterfield, Lava Fields), set terrain scale and water level, and generate in seconds.
-
Map-style regions — lay biomes out on a top-down realm grid. Generate a cell next to an existing one and the borders blend into a continuous world, instead of a single flat noise blob.
-
Realistic or blocky — the same presets can produce smooth realistic terrain or a clean blocky style.
-
Built-in quality report — a readable score with smoothness, seam, material, and fill diagnostics, so you can check the output instead of eyeballing it.
-
100% local & offline — no cloud, no API keys, no external calls.
-
Clear + Undo for fast iteration.
Why team built it
We’re building a series of games set in procedurally generated biome worlds, and I
kept wanting to lay biomes out like a map and have their borders blend automatically instead of fighting one big noise blob — then get an objective read on whether the result is actually clean. TerrainSuite is that workflow.
The timing feels right, too: Roblox’s Terrain Early Access Program is expanding terrain from 23 to 64 custom materials and cutting client memory 40–60% with ~2x faster loading, so much larger, richer terrain worlds are becoming practical. A region/border workflow like this is built for exactly that kind of large, multi-biome map. TerrainSuite doesn’t require the Early Access Program, though — it runs entirely on standard Studio terrain APIs today, and we plan to grow the presets and materials alongside those engine improvements as they roll out.
What I’m looking for — feedback on the workflow
This is an early free release. The main thing I want feedback on is the region + border-blending workflow itself:
-
Does laying biomes out on a map grid match how you’d plan a world?
-
Which biome presets would you want next?
-
Would you reach for this over hand-sculpting terrain — and if not, what’s missing?
-
How useful automatic scattering (trees, rocks, props) and path/river/cave carving would be on top of a generated region.
-
Whether you’d want custom biome presets defined in code for runtime generation, or if edit‑time generation in Studio is enough for your use case.
Update 2026-09-15T22:00:00Z: Realm persistence, custom presets, and smoother borders
TerrainSuite Demo has grown substantially since the original post:
-
Your realm now persists. Generated regions, realm boundaries, selected presets, and slider settings are stored locally in
ServerStorage._TerrainSuiteafter you make changes, then restored when you reopen the place. -
A tighter preset gallery. The smaller gallery is easier to scan and now includes two more refined built-ins: Tropical Island and Desert Plain.
-
Custom presets. Save your current settings as a named preset, rename or delete it later, and keep it beside the five built-ins. Presets are readable ModuleScripts, so advanced users can also inspect and adjust their material rules directly in Explorer. Reset to Preset Defaults reloads the saved preset values.
-
Better region seams. Adjacent regions now meet as a continuous terrain surface, including their water edges, instead of showing a visible step at the border.
Scatter, caves/carving, and Guided and Improve generation are planned for later updates. I am also exploring AI assistant-friendly preset resources for creators who want help authoring custom biomes.
Any feedback is appreciated - thanks for taking a look!
