Many things (mods) we could never thought that they were possible,however many skilled modders show us with great mods or even "small" ones this : Skyrim's engine is very sensitive and has limits BUT without trying something you can not say "it's not possible" and surely you can not say that if your don't like something(or doesn't really bother you) doesn't worth even a try. I am not skilled and yet I've tried to check on which conditions sun makes shadows with no luck. Maybe few skilled modders tried and failed,some because this is beyond their skills,other because maybe they do know that it's impossible,who knows.The fact is that it would be awesome,not only for me but for everyone who play this game. I never said that I don't respect modders and their work,small or huge.I too believe that some people think that and I've seen many posts asking/requesting "crazy stuff" but I am not one of them...
