GeNa Pro - Level Designer, Villages, Roads & Rivers for Unity 6 is a sophisticated level design system that enables you to rapidly and intuitively create beautiful levels for your game or simulation

Create beautiful scenes fast with GeNa Pro!

GeNa Pro saves 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!

Why should you buy GeNa Pro?

GeNa Pro can spawn anything! It can make forests, rivers and roads along splines, place buildings and automatically clear and flatten the terrain.

It 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.

The benefits of GeNa Pro include:

Easy to use
Nicer environments
Massive time savings
Replicable quality through automation
Better frame rates (dependent on situation)
Better lighting
Fun!

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 VS (Best Artistic Tool - Unity Awards 2020, Best Development Tool - Unity Awards 2024) 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.

As a FREE bonus, GeNa Pro comes with spawner packs for Gaia Pro VS, 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!

GeNa Pro consists of the following major components:

GeNa Spawners: Spawn assets into scenes.

GeNa Map Builder: Procedurally create and connects towns.

GeNa Decorators: Decorate assets with logic that influences spawning.

Spawns textures, grasses, trees, prefabs, structures, towns, rivers, roads.
Automated map generation system finds optimal spaces for villages, spawns them, and then connects them with roads.
