WELCOME TO GAIA 2

Welcome to GAIA 2, the all in one landscape, terrain and scene generation system for Unity that allows you to create stunning mobile, vr, desktop and console scenes in minutes!

GAIA 2 gives you the flexibility to go fully procedural or fully manual or somewhere in between and delivers simple, fast and pretty terra-forming, texturing, planting and placement using our sample assets or yours as you prefer.

GAIA 2 saves you time, money and heartache by automating the setup of your render pipeline, character, sounds, water, skies, post fx and lighting, so that you can be up and running around in your scene in minutes.

Try Gaia 2 first, and then upgrade to the raw power of Gaia Pro! Gaia Pro offers more creative options, over one hundred photogrametry enhanced assets and biomes, massive worlds with integrated streaming, time of day, skies, weather, birds, butterflies, pollens and other vfx, sound fx and music, and much more.
