Hi there,

I need to use a toon shader in a night scene-- but everything I've managed with it looks simply bright and daytime, regardless of the brightness I set in the sun (e.g. 0 or -100).

Can someone please tell me a good way to get a night effect with a toon shader? Here's what I'm using..

skin1=toonlookup_bmp;

pass p0 // shade it
