    About

    In practice. What you can do with Gaea.

    Gaea builds procedural 3D terrains through a node graph, and is used as a reference tool for landscape and environment work in games and VFX. Paid editions add tiled builds at very high resolution, Houdini support, and macro-based automation on top of the free, non-commercial Community edition.

    The entry commercial license, Indie, costs 99 USD once, with no subscription, but is node-locked to two computers and excludes Houdini and macro creation. Freelancers and small studios under 1M USD in annual revenue fit the Indie or Professional editions; above that threshold, the more expensive Enterprise edition is required by the license terms.

    Practical uses

    • Game studioGenerate a large, tiled terrain heightmap procedurally, then bring it into Unreal Engine for a level.
    • Freelance 3D artistBuy the Indie license once to produce commercial landscape renders without a recurring subscription.

    Our verdict. What to know about Gaea.

    How the score breaks down

    Added value

    A one-time 99 USD Indie license covers commercial terrain work indefinitely, with no recurring subscription, which is cheap relative to the category.

    Simplicity

    Neutral score: the time needed to produce a first usable terrain is not covered by the collected sources.

    Fit for purpose

    The tool is described as a standard for procedural terrain generation, with tiled builds at very high resolution confirmed on paid editions.

    Performance

    Support for tiled builds up to 262,144x262,144 and macro-based automation on the higher tiers point to a high capability ceiling in the category.

    Reversibility

    Neutral score: export formats and data portability out of Gaea are not covered by the collected sources.
