I have a few cool announcements about CGE features this weekend 🙂 Let’s start with a summary of new things done lately:

1. Fixed bold / non-bold display in CGE editor for _Single_ properties. Bold in object inspector should always mean _“different than default”_ intuitively.

2. I have started implementation of the `EnvironmentLight` X3D node, to perform image-based lighting. This is a work-in-progress. The eventual goal is to add such light to CGE, and to X3D 4.1, and to make it consistent with glTF image-based lighting extension. See [X3D 4 plans](https://github.com/michaliskambi/x3d-tests/wiki/X3D-version-4:-New-features-of-materials,-lights-and-textures#deferred-to-x3d-41-new-environmentlight-node) and [initial EnvironmentLight tests](https://github.com/michaliskambi/x3d-tests/tree/master/pbr/environment_light).

3. The `run` command of our [build tool](https://github.com/castle-engine/castle-engine/wiki/Build-Tool) is now more useful on Windows. It shows the log, just like on all other platforms (desktop Unix, mobile…). So using `castle-engine run` on command-line is now very useful on Windows. 

4. Additions and fixes to [CastleTransform](https://castle-engine.io/apidoc-unstable/html/CastleTransform.html) API:
