A updated shadows tutorial for custom stages (I solved it myself like a badass)

[Nezha B. Rose]

Is anyone here willing to share their knowledge on how to make shadows in custom stages? I been reading the tutorials found here but its too hard to understand or is too sumarized. A knowledge like this could be extremely helpfull for stagers. If I learn it I could keep updating it myself later...

Edit: I learned how to do it myself. Yay!
