Notes

In this release we've changed the lighting model used for 3D lighting. Previously lighting was based on a Phong model, with materials using a 'shininess' factor. We've now changed it to a Physically Based Rendering (PBR) lighting model, with materials using 'metallic' and 'roughness' factors. We considered supporting both lighting models, but PBR looks to be the industry standard right now with better interoperability, and supporting only one lighting model is a significant simplification for the engine. If you still think we should support the older lighting model, we'd be interested to know why, so let us know. This is a breaking change, and projects using actions/expressions relating to the old material properties will not open unless they are removed from the project. However 3D lighting was only introduced in last week's beta release, and beta releases are the place to make any such changes before it reaches a stable release where the backwards compatibility requirements are stricter.

There are other 3D lighting improvements, including a new Transmissiveness property. This affects how much light comes through a 2D object like a Sprite when the light is on the far side. When transmissiveness is 0% the object will appear in complete shadow, whereas when transmissiveness is 100% the object will appear lit up the same as it is on the opposite side facing the light. There's also a fix for 2D objects not being lit up equally on both sides.

This release also has further improvements for 3D models: now you can import or replace multiple models at a time, and the Asset Browser now has support for 3D models via .gltf and .glb files. As ever there's a range of bug fixes, including for 3D models and the 3D editor. Happy testing!
