hello, 

i wanted to use a while-loop in blob-function. but all i get is an 
error-message that at least one component is needed in a blob. who can help?
code follows. thanks in advance.

#include "colors.inc"

#declare cam1=
camera{location <0,0.2,-1> look_at <0,0,0>
}

camera {cam1}

light_source{
        <0,2,-2>
        color White
}

background{
        color White
}

plane{
        y,0
        pigment{color White}
}

#declare blob_tex = texture {pigment {color White}}
#declare blob_fin = finish {
        phong 0.5
        reflection 0.01
        diffuse 0.6
}

blob{
#local anz = 5;
#local counter = 1;
        threshold 0.1
        while(counter <= anz)
        sphere{
                <0.1*counter,0.1,0>,0.1, 1
                texture{blob_tex}
                finish{blob_fin}
        }
        #local counter = counter + 1;
        #end//while
}

Hi!
You forgot a "#" before the while, so "#while" instead of "while" will work.
Best regards,

Nah - my trick is to put the "blob{" within the while loop ;)
