GeNa Pro - Terrains, Villages, Roads & Rivers


Create beautiful scenes fast with GeNa Pro!

Purchase GeNa Pro today to save time and money by creating beautiful levels for your game so that you can focus on the game play that matters and get to market faster.

Great level design is fun until it's not! Manually shaping your terrain and perfectly placing tens of thousands of objects into your scene is a meticulous process that takes huge amounts of time, and more often than not will look bland as designer fatigue sets in.

By comparison, GeNa Pro gives you what you want, where you want it, and perfectly adapted to it's environment in a fraction of the time that it would take to do by hand. And if you don't like what GeNa does for you the first time then hit 'iterate' until you do and GeNa will create variations for you!

GeNa Pro can spawn anything. It can make forests, rivers and roads along splines, place buildings and automatically clear and flatten the terrain, and can even make entire maps as it intelligently scans your terrain and chooses the best places to create villages and towns and connect them with roads. It is incredible how powerful GeNa is.

GeNa Pro also comes with a powerful decorator system that allows you to influence how your content is placed into your scene. Flatten terrain and clear trees and details under your buildings, snap things to the ground, add in random variation, create sophisticated super spawners out of libraries of sub spawners and much more!

GeNa Pro is the perfect companion to Gaia Pro 2021 (Best Artistic Tool - Unity Awards 2020) by design, and was inspired by our collaboration with Crowfall where GeNa and Gaia were used extensively! In fact in the video on their home page Gaia & GeNa created the environment, and Pegasus did the camera fly throughs and character movement. Good tools and amazing talent makes magic!

As powerful at runtime as it is at design time, GeNa Pro was designed with runtime API control and extensibility in mind, so you can extend GeNa Pro and embed it into your own solutions.

As a FREE bonus, GeNa Pro comes with spawner packs for Gaia Pro 2021, and the free Flooded Grounds modular asset pack so that it is simple and fast to create environments that 'just work', and you can be up and running in your own amazing levels within minutes. Keep an eye out as we introduce more spawner packs in the future!
