Wait, so outline can be rendered in the same pass?

TSK TSK POIYOMI
YOU GOT SUM WORK TO DO!!! 

[spoiler]Im only half kidding, but please make it on par with Silents thanks <3[/spoiler]

So like, the way outlines work in my mind is you just z pass render behind an entire another scaled mesh, right?

How does silents work if it is 1 pass? i always feel guilty for using outlines but I didnt know you could make it 1 pass, please teach me the technical details thanks
