Alright so I may have gotten distracted, but I wanted to implement something kind of cool...
One thing that was missing was very high clouds, like cirrus and cirrocumulus clouds. After a bit of shader magic, I can officially say it looks really cool and definitely fills in the space. Honestly surprised I didn't think of doing this sooner!
Right now they aren't customizable, but they can be, as show in these images. Customizability will not be as advanced as the normal clouds are, but definitely some level of configuration would be added.
Anyways, I need to finish the cloud regions and get a BETA out for you guys! Until next week.
