As I'm sure a few of you know, You cannot use all stencil shadows. They are only able to display on players (Despite being able to work on everything.)
BUT! With my new technique (stolen from 2012 comment section.) Theres a better way!
Spawn a model, Put a humanoid in the model, Do the same with a part. It should have a stencil style shadow.
This is very broken, Sometimes just doesn't work, And for some reason wont display on my cone hat. But hey! Atleast it works.. Sorta..
