STRATUM
v1.0Your terrain workflow, on autopilot.
Your terrains land in Unreal Engine or Unity with meshes, textures and materials already set up.
One tool between your terrain and your game.
Procedural tools make a terrain in minutes. Everything after still eats your days: renaming, sorting folders, exporting, re-importing, building materials, asset by asset. Stratum automates that whole second half, from your Gaea graph to assets ready in your engine.
Who produce in batches: packs, variants, whole biomes.
Renaming, sorting, re-importing, building materials, by hand.
Per terrain set. Your assets land named, sorted and ready.
Why did I build this tool?
Simple: Stratum started as a personal tool I built while making terrain packs. The thing is, I spent far more time juggling between software than actually working in it: exporting each variant, renaming files, organizing folders, re-importing everything into the game engine, building materials... I repeated the same clicks for hours on every pack, it was a huge time sink. So I automated the process, step by step, until a single click did it all. Today every Kalysteon pack goes through this tool, and now it's yours to use. Hopefully it helps you too!

Questions, answered.
What do I need installed to use Stratum?
Gaea 2 Professional or Enterprise, plus Unreal Engine or Unity for the import stage. Houdini is optional. Stratum drives those tools, it does not replace them.
Does it work with Gaea Community?
No. Stratum builds your graphs through Gaea's command line, which is reserved for Gaea 2 Professional and Enterprise. You can still use the Houdini and engine stages on meshes you already have.
Can I use it without Houdini?
Yes. Every stage can be switched off. Gaea straight to Unreal, Gaea straight to Unity, or Gaea on its own are all valid runs.
How do updates work?
Stratum tells you when a new version is out. Download the installer and run it over the current one: your projects, settings and license stay in place.
What happens after the first year?
Your license never expires: Stratum keeps working, with every version released during your year of updates. To keep getting new versions, renew for $22.99/year (Indie) or $81.99/year (Studio), cancel anytime. Renew with the same email as your purchase, straight from Stratum (Settings, License).
Can I sell games made with Stratum terrains?
With an Indie or Studio license, yes. The free tier is personal and non-commercial. Terrains you generate belong to you in every tier.
