Gaia is one of those “Go To” tools that you’ll regret if you never buy it, with it’s easy to use tools and interfaces, you’ll have a beautiful terrain setup in your scene in no time. Gaia was created from the ground up with the vision that not only should the creation process be fast but fluid as well, giving the developer a break and freed up for more time to focus on other aspects of the project or game.

Fortunately Gaia delivers on that and you can really tell how well thought out and dedicated the team have been to making Gaia one of the best tools it can possibly be.



Scenes like the one above can be made using a combination of Gaia & CTS (another Procedural Worlds asset), pumping up the power you can get out of each asset. A really powerful tool Gaia offers is precise terrain texturing, foliage and object placement, which means you can literally indicate in the settings the requirements for each to spawn at.

This really gives you a huge boost in customization and making your terrain that much more custom for your project, rock placement, buildings, towns, you name it, you can indicate what spawns where and Gaia handles the rest. This offers a lot for one time generation or procedural generation, open world games or small areas, truly controlling how the environment is birthed and giving you the power of a God!

Texture, foliage and object spawning are just a few of the many features Gaia has to offer, allowing you make incredibly large terrains with ease and giving you the tools to optimize the heck out of your terrain, like the powerful terrain smoother which smooths out those jagged edges of your terrain, reducing triangle count and increasing performance, something that for large terrains can be a major game changer.

Reaching sizes of up to 16K sq meters, world size terrains is within grasp and entirely customize able through Gaia, Gaia creates, caresses and improves every aspect of your terrain, just like a loving goddess would.



Gaia comes fully integrated with options for desktop, mobile, vr and other platform terrain creation, tools like first person setups, water setup and post process instant integration make scene creation so easy, it still amazes me to this day each time i make a scene with Gaia.

Gaia was the first to create and utilize Stamping for unity terrains, as many know generating terrains, especially detailed ones can come at a cost of time but Gaia’s Stamping system gives you an option to generate fully detailed terrains, just by using stamp maps or textures, which can be viewed in the editor mode prior to stamping.

Stamping a terrain is not like painting, you can stamp an entire terrain with one stamp or use various stamps to shape certain areas of the terrain, customizing the size, height, shape, etc., of the stamp, pushing customization yet again to another level.

Gaia integrates with the available Gaia stamp packs available on the asset store, currently there are dozens of stamps available offers any type of terrain you can imagine. So the question is, do you have to use the custom Gaia stamps?

The answer is no! You can generate your own custom stamps and use those to create your dream terrain, tutorials and tips are up on the Procedural Worlds website.



Now that you know how powerful Gaia can be, there’s only one thing to do and that’s dive on in!
