It seems as though povray has a hard time layering more than four
transparent surfaces on top of each other. Am I correct? Is this a
known issue? Or is it my version of Pov? (currently 3.00e, 3.02 won't
run)
Run this source and it should be fine, but change the loop from .4 to .5
and the last layer's transparent color will turn black.
---BEGIN POV FILE---
camera { location -z look_at 0 }
light_source { <0,0,-1> rgb 1 }
light_source { <0,0,1.5> rgb 1 }
#declare c=0
#while (c<.4) /* <-- change this to .5 */
plane { z,0
pigment { checker rgb x, rgbt<.5,.5,.5,1> scale .2 }
translate <0,0,c>
}
#declare c=c+.1
#end
plane { z,2 pigment { rgb 1 } }
---END POV FILE---
Maybe I don't know about an option somewhere to increase the depth at
which pov traces through transparent textures, if so please tell me!
Thnks much

global_settings {
max_trace_level 5
}
Increase the integer to increase the number of tranparent surfaces POV will
bother with.

try setting your max_trace_level higher

Have a good one, Maleko

Hmm... looks like i'll be spending a lot of time waiting for my image to
trace. Either that or I'll use a height field. (see my IRTC stills
image if I get around to finishing it)
I knew it was somewhere!, thanks Mike

max_trace_level... The most elusive of POV features ;)
I should know, I hacked my brains, cursed and RTFM at least 2 times before
I got it.
Perhaps there should be a big notice about it at the POV webpage (well, at
least sth. to this effect), since this question is often asked (and reported
as a bug at least once).
