Here's a quick include file that I use to block Lens Flares in pov.
You'll need SuperPatch or MegaPov to run it, though. Oh, I've got this
setup for NKFlare, but you can probably set it up for Colefax's too.
Here are the new declares:
#declare Distribution = 1/5
Distribution of rays around the Lens Flare location (usually the radius
of the object giving off light)
#declare BlockObject = union {Obj}
Object that will block the Lens Flare.
#declare MaskType = 1
Type of masking. 1 is scale and brightness, 2 is brightness, 3 is
scale. Try them and see what I mean.
#declare MinimumAmount = 0
Minimum amount of light needed before the lens flare cuts out.
#include "FLRBLKR1.inc"
Replaces #include "NKFlare.inc"
That about sums it up. You can use any object, any flare, any
brightness, any size. The only thing that needs to be is that the new
declares come after the old declares. There is one limitation that I
can think of. You can't have a flare on the surface of a object and
have it block the flare correctly. Dunno how to fix this.
Can't think of anything else.
Comments??
