Darkening Rendermode Additives?

Lazer

I'm trying to make a fan shadow effect like the one seen on ns_hera for an area near one of my hives. I have everything working, but the shadow's rendermode doesn;t seem to be working right. I want to use an additive one, but I don't want it full bright.

EDIT: nvm, I can't believe I didn't figure this out sooner. Please delete this post.

Nay

ermm set the fx amount down to like 96 or something
