Maya 2020 fundamentals - modelling the real world
Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

I don't think the physical sky can do that, plus I think its a bad idea to use a directional light for emitting photons. I did a post on caustics . Hope that helps.
