Assets and Content:

Book of the Dead: Biome for Gaia Pro VS (please note that Gaia does not contain GTS)

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
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 and Gaia Pro VS are 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

Sample Biomes & Assets

Gaia for Unity 6 comes with a minimal set of sample assets to give you a sense of what Gaia does, and to help you to learn how to use them. This helps to keep the price and installation size down.

You can then choose your assets and customize the look and feel of your world to your taste, or you can upgrade to Gaia Pro VS for a much larger set of photogrametry-based assets and biomes.

In addition to the assets that come with Gaia, we are pleased to include sample assets from NatureManufacture, Synty Studios and 3D Forge.

With Gaia Version 4.2.0, we now include assets from the popular "Book of the Dead" Unity Demo to provide you a complete forest biome that you can spawn and use in your own projects.

What additional features does Gaia Pro VS offer over Gaia for Unity 6?

Gaia Pro VS offers the following additional features. There is an upgrade fee to convert Gaia to Gaia Pro VS.

The things that Gaia Pro VS adds to Gaia include:

Unity Verified Solution certification
Massive world support with streaming
Additional stamping, erosion & masking operations
Stylized low-poly & impostor mesh terrain conversion
Over 70 additional photogrammetry enhanced assets & presets
Terrain addition/deletion support - dynamically grow your world
Biome-based stamping - shape your terrain as part of your biome
MMO-friendly export for client/server (colliders / addressables)
Terrain stitching - dynamically connect terrains to remove gaps
Weather system with rain and snow support (Built-In and URP)
Multiple skies, lighting, VFX & sound fx systems
GAIA API - call Gaia functions within the editor.

These additional features provide a more refined world-building experience that allow you to bring your creative ideas to life faster and with higher production value.

Video montage notes

The introductory video montage shows a range of scenes created with Gaia Pro and other assets and tools from the Asset Store. The workflow for Gaia and Gaia Pro is largely identical, as the two products share 95% of the same code base.

The intention here 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.

Release Notes

Gaia Pro VS 4.2.2

Added new statues and other prop assets to the "Book of the Dead" biome
Added the ability to filter spawn rules by render pipeline
Fixed bugs with the terrain fixing manager tool

Gaia 4.2.1

Fixed a bug where Gaia would always display the HDRP water info dialogue again.

Gaia 4.2.0

Free "Book of the Dead" biome package: For this update we created a free biome package for the popular "Book of the Dead" Unity demo! This package can be used to easily bring the high quality vegetation and environment assets from the "Book of the Dead" demo to your own scenes. This package is included directly in Gaia for Unity 6, a similar update for Gaia Pro VS will follow shortly.
Added an option to enable dynamic resolution scaling in the player setup when running in HDRP.
Fixed a bug where a spawner could run forever after stamping on the terrain
Lighting tweaks for the HDRP lighting presets.
Fixed a bug where the target platform in the gaia manager would switch to "Custom" by itself.
Fixed saving and handling issues with the terrain detail overwrite system.
Fixed an issue with collision masks in HDRP that could lead to reduced spawn counts.

Gaia 4.1.5

Fixed issue where the shadow settings from the system check would not save
Removed dependencies to Gaia Water from the URP underwater setup
Fixed issue where the sea level was not set up correctly in the URP underwater effects
Removed old / outdated "Procedural Worlds Sky" lighting preset

Gaia 4.1.4

Reviewed for compatibility with Unity version 6.2
Extended the functionality of the Terrain Stitching tool into a Terrain Fixing tool: This tool can now fix heightmap gaps between Terrains, fix texture seams across Terrain borders and remove heightmap terraces. You can find this tool in the Advanced Tab of the Gaia Manager under Tools.
Gaia Manager will now recognize existing Terrains made outside of Gaia better. It will offer to ingest those Terrains when you try to create a new world with already existing Terrains in the Scene. This is especially helpful in combination when importing real world heightmap data from Storm.
Reworked the main lighting Presets for URP and HDRP (Day, Night, Morning, Evening). The older lighting presets are still available as legacy unitypackages that you can install if you still want to use those.
Added a feature to height adjust the fog for the lighting presets so it better adapts to different Terrain sizes
The Biome Controller now has two Buttons, one for spawning within the range and one "Spawn World" button that will spawn everywhere. (Same logic / workflow as with the spawners)
Added fog blending to the URP cubemap shader - this will render a bit of the fog Color of the Scene at the horizon in the skybox - this helps bleding your fog seamlessly with the skybox.
Fixed various issues with collision masks in URP and HDRP
Migrated the checks for URP shadow distance and cascades into a single check as they could interfere with each other
Fixed issues with render Pipeline detection if a Pipeline asset was used in the Quality Settings but no Default render Pipeline asset was set in the Graphics Settings
The session recording is optional now and off by Default. This Speeds up processing in Gaia a bit, since it does not need to create / process the session entries anymore
Reduced smoothness of the Terrain textures in the Gaia spawners

Gaia 4.1.3

Reviewed for compatibility with Unity version 6.1
Added the the water from the Unity URP 3D Sample pack and combined it with the Underwater effects from Gaia. You can use this water as alternative to the Gaia water. This water works with Screen Space Reflections and is compatible with single-pass rendering in VR.
Added a check for sensible shadow settings in URP.
Tweaked HDRP Daytime lighting for better contrast between light and shadows
Added a new "Nordic cool lighting" preset for HDRP
Automatically install Storm shaders for Gaia when Storm is already present in the project
Added capability for Storm vegetation color baking in the Terrain Converter
Fixed an issue with collision mask baking in URP in combination with the URP "Opaque Texture" setting
Fixed scene view slowdowns stemming from the Gaia scene view panel and the Gaia Manager
Added back the ability to increase/decrease the flying speed of the fly cam with the scrollwheel when using the input system
Made the simple layer culling script work better when used in a prefab

Gaia 4.1.2

Renamed Gaia 2023 to Gaia
Fixed a bug where the collision mask output could be flipped in URP
Fixed a bug with spawners not being listed in the Gaia Manager correctly

Gaia 2023 v 4.1.1

Aligned version number with Gaia Pro

Gaia 2023 v 4.1.0

Added new Polygon Mask: Freely draw a polygon shape to spawn biomes, textures, etc. inside
Improved Stamp images to show less scaling artifacts when stamps are greatly scaled up across a wide and large area
Improved compatibility with different versions of Cinemachine
Updated Quick Start PDF with more information for the new Polygon Mask and Terrain Loading.
Fixed an issue with Grow and Shrink Mask scaling
Fixed an issue with alignment of the noise masks across multiple terrains

Gaia 2023 v 4.0.9

Added compatibility with Unity 6 (please see notes below)
Added optional "Dynamic Depth Of Field" component when using lighting presets
Updated URP "Day" lighting preset
Added a max shadow distance check for URP
Added a quick light bake setting for lighting presets in URP
Switched to GPU instanced grass in sample Synty biome
Fixed a bug where the Gaia Maintenance would error on problematic prefabs
Fixed a bug where the Gaia Distances on the Terrain Detail Overwrite script were not initialized correctly

Notes on compatibility with Unity 6:

The Unity Input system package does not seem to require a restart anymore in Unity 6 like it did in earlier Unity versions. During testing we noticed this can lead to odd error messages in the console, and code not compiling anymore. If you install the Input System package (as advised from the Gaia Manager), it is recommended to restart the Unity Editor afterwards to avoid such issues.
In HDRP there are various settings for the HDRP water system. In Unity 6 those settings do not seem to be accessible anymore through scripting which is why we cannot enable the water system automatically for you anymore. If you intend to use the HDRP water, please read the Water System documentation in the HDRP Manual and make sure your project is set up to use HDRP water with the required features.

Gaia 2023 v 4.0.8

Improved handling for "unsafe" special characters in biome & spawner names when saving the biome.
Added an option to use a VR-friendly water shader for the Gaia Water in URP
Fixed a bug where the world designer would initially not use the correct tile height as shown in the Gaia Manager
Fixed a bug where switching between unity and another application during world creation could lead to problems with the generated terrains.
Fixed a bug with the Fly cam script when building for Android
Fixed "shiny" terrain textures in URP in the synty biome
Fixed issues with exporting from the world designer when the terrains from a previous run were turned into prefabs
Added a check on package import that will add biomes from spawner packs automatically to the Gaia Manager
Fixed a bug with water height when creating new scenes with different sea level
Fixed player spawning under water when there was a lake in the middle of the created terrain
Fixed a bug where custom lighting presets would fall back to the original Gaia profiles when the scene was not saved before closing it
Fixed visual issues with the lighting setup in HDRP

Gaia 2023 v 4.0.7

Fixed compile errors due to the irregular removal of the "numberOfBounces" HDRP sky property in the latest Unity 2022.3 LTS releases
Removed "additional HD" camera component from the flycam prefab as it would display as "missing component" in other pipelines
Fixed a bug where the depth ramp texture of the Gaia water would reset after customizing it
Fixed a layout issue when setting up a tree collision mask without tree spawners in the scene
Fixed issues with the HDRP water setup where the water would not appear or the scene would not save the added water

Gaia 2023 v 4.0.6
