What's new in Gaea

This is a patch for the previous release,, that fixes a few key issues.

For the major updates in 1.2 itself, see the Gaea 1.2.1 blog post.

NOTE: If you are using the Houdini Bridge and are relying on .TOR file created before, we recommend opening the file in Gaea and letting it upgrade the nodes.

  • Fixed an incompatibility with the Houdini Bridge.
  • Fixed a rare crash in Islands node.
  • Synth would create grayscale data upon rotation.

What is a Bleeding Edge build?

Bleeding Edge builds are early access builds with features currently in development. They are mostly stable, but not fully ready for production.

You get to try new features as they're added, and provide feedback very early so we can modify them to your satisfaction.

Bleeding Edge and Production Ready versions install to different locations, and do not share settings or registry entries. This gives you the flexibility to try new features without endangering your work projects.

What's new in Gaea 1.3 Bleeding Edge?

This our largest update to date. This will also become our Long Term Support (LTS) release when released under the Production Ready channel.

For the major updates in 1.3 itself, see the Gaea 1.3 Bleeding Edge blog post. Please read the Breaking Changes section in the blog post before trying this build with any existing projects. Some features mentioned in the changelog below may not be available in the initial Bleeding Edge build. See the blog post for details.
