You are like an Archetype, that from which all other molds can/should be made.

I read your stuff and think, I couldn't even talk to this guy cause I wouldn't
be able to keep up, thinks like 10 times my meager capacity. ouch!

Just love it when this god posts!!!!!!!!!!!!!!!!!!!!!!!!!

oh and if anyone has an answer, trying to set AA with focal blur and:

Cleanup Parse Warning: Focal blur is used. Standard antialiasing is switched
off.

this is because .... ?
never together or there are some other requirements?

Love the blur but there are choppy pixels in the focal area.


; ppm (portable pixel map)
+fp
Antialias=On

Sampling_Method=1
; default 1

Antialias_Threshold=0.3
; If the color of a pixel differs from its neighbors (to the left or above)
; by at least the set threshold value then the pixel is super-sampled by
shooting a given,
; fixed number of additional rays. The default threshold is 0.3

Antialias_Depth=2
; = 4 samples per pix
; default 3 = 9 or 81 +am1 or 2
