I'm sorting a project out into passes, and i've got a self shadow pass.
The object has a usebackground shader applied to it, with all relectivity setting turned off.
I have my lights emitting shadows only, and have turned FG off, and the geometry is smooth.
So then, why does it look like i've rendered it in a toon shader or something? Those alpha shades shouldn't be so crisp like that. You can see some of it working correctly (the grainy bits) but the rest is waaaaaay off.
Is there any thing i'm doing wrong here? Any Ideas?
