Re: Bump Mapping and Camera Projections?

[André Adam <a_adam(at)49games.de>]

I hope nobody minds if I jump in here (hey, it's my thread! ;) ), 
Halfdan, the camera projection workflow you suggest doesn't seem work 
over here, unless I uncheck the clamp option as Fred suggested earlier.
Honestly, I'm fine with that and can work around it. I didn't start this 
thread to bash on XSI's bump mapping implementation, but to verify if I 
did something wrong with my setup, as clamped bump mapping with cam 
projection would have been a welcome shortcut to a lot of bump mapping 
work to be done in the next couple of days...
I like that Voodoo doll thing, btw... :)

Cheers!

I have a voodoo doll of the individual who suggested the bump map settings should be on every single texture node. You practically can't see the doll now for all the needles.
