Craft Stunning 3D Worlds in Minutes with Gaia Pro for Unity 2021!

Create stunning game worlds and environments for console, desktop, mobile, switch & VR.

Gaia makes generating detailed lansdcapes, terrains and levels easy and fast. It saves you weeks and months of work so that you can focus on creating the gameplay that matters.

Gaia is used by over 150,000 game developers, and has been continually developed and constantly supported since its launch in 2015.

Why should you buy Gaia?

Gaia gives you the workflow you prefer, from artist-driven to fully procedural, to deliver simple, fast, and pretty terra-forming, texturing, planting and placement for everything from low poly stylized through to high-end photo-realistic environments.​

The benefits of Gaia include:

• intuitive rapid visual iteration
• fast terrain and scene streaming
• breaks terrain into separate scenes - supports team development
• battle tested support for massive worlds with hundreds of terrains
• longevity in the asset store - will always be supported
• customisable biomes to create any look you want
• reusable biomes on any terrain in any scene
• compatible, works with anything

​

Supports terrain, trees, grass, water and any other intricate biome you wish to create. Also works with GeNa roads and rivers to form a complete world creation platform, GTS for enhanced terrain rendering, and Ambient Sounds for beautiful soundscapes.

Gaia saves time, money, and frustration, by integrating what would typically be many expensive and complicated systems into one simple wizard-based system that automates the majority of the effort needed to make playable levels.​

Gaia is used in education, defense, simulations, and games such as Zenith, Last Epoch, and Crowfall.

Easy workflow for rapid prototyping and iteration

• Select your world size, biome, and target platform
• Procedurally (or manually) generate your base terrain
• Procedurally texture, plant, and populate based on the biome you choose
• Optionally export versions of your world optimized for vr, mobile or MMO's
• Set your lighting, wind, water, controllers, culling, and post fx with a click
• Press play and explore your world
• Iterate as needed

Video montage notes

The introductory video montage shows a range of scenes created with Gaia and other assets and tools from the Asset Store. The intention is to show that magic can happen when you combine tools with art and add a dash of creativity and effort. The video flythroughs were created using Pegasus and recorded with Unity Recorder.
