[SOLVED] No fog rendered in v2.0.0-alpha?

I'm trying the nightly builds of 2.0 for Forge in MC 1.20, default DH settings, single player and no shaders, nor other mods loaded. As can be seen in the picture, regardless the LOD generation is still in progress, it looks like there is no fog rendered at all. Is that the expected behavior? If there should be fog instead, is there any setting I should try tweaking? Thanks!!!
