Release 1.2.0

Release 1.2.0

Our most powerful release yet brings some first post-processing like Bloom and Tonemapping, HDR environment support, improvements to image-based lighting, animation blending, morph targets, and a JavaScript/Typescript based editor API to write custom tools.

Enhanced Testing 

We created a testing framework that can compare the rendering results of a project to automatically test our examples.

We open-sourced this framework to allow you to test your own projects.

Invisible Changes 

This release is full of invisible ground-work to ensure the architecture of the engine and editor scale with upcoming features:

  • We refactored the internal data model for the editor to be more maintainable, faster, and catch errors.
  • The animation system now uses animation graphs. While they are not exposed to you yet, they already enable new features like animation blending.
  • Multiple scenes are now handled at runtime. This is already useful when appending and loading scenes from JavaScript, but will soon allow efficiently managing resources throughout multiple scenes and resource bundles from the editor as well.
  • The serialization format for custom components was changed to support many more property types in the future.



  • Add “Animation tools” view for adding event tracks to animations
  • Add JavaScript/Typescript based Editor Plugin API to build custom views and tools
  • Add 1D and 2D blending support to animation component
  • Restyle the UI, fixing many UX issues and using the window space more effectively
