There will be a News Announcement soon.
But in the meantime enjoy the pictures
HDR sample's "Heavy overcast" preset now finally has a lot more atmosphere put into it.
There is a new sample in Samples/2.0/ApiUsage/Atmosphere to showcase its controls.
The samples PbsMaterials, HDR and Tutorial_Terrain enable it by default (when the Atmosphere component is built, which is on by default).
HlmsPbs and HlmsTerra have been updated to integrate its fog.
