Here are the source files for the 1 Layer Clouds.
As always, let me know if there are any issues with the files, or improvements/suggestions on how to make it better. I have a feeling I'll be continuously revisiting and improving this approach in the future - clouds are just such a beautiful phenomenon in nature, and attempting to capture that in a real time shader is a real pleasure.
Thanks so much for all the support. I hope everybody has a Merry Christmas, and I'm looking forward to more shader fun in 2019.
