Hi,

I am trying to generate the html files in the portfolio directory.
I get the error below in a lot of the files.

  Parse Error, Negative Subscript


   light_source {<-500,300,-500> rgb 1}
   light_source {<500,500,500> rgb 0.7 shadowless}

   union {
      plane {y, 0}
      sphere{
         0,1
         scale <0.6,0.3,0.6>
         translate<0.55,0,0.5>
      }
      pigment{pigmentArr[frame_number-1]} /*** error here ***/
   }

Another example is in c_colors.pov

   light_group {
      light_source {<-50,500,-200> rgb 1}
      union {
         plane {y, 0 no_shadow}
         difference {
            sphere{0,1}
            box{<-1,0.9,-1>,<1,1.1,1>}
         }
         translate <0.7,0,0>
         pigment{colorArr[frame_number-1]} /*** error here ***/
      }
   }

frame_number is an internal variable, looks like it is relative to animations.
Are animations turned on when you render? (check your messages from the
rendering process)

Greetings,

which version ?
You must be aware that the portfolio must be rendered by the ini files, 
not the pov files directly (unix version get a readme.txt , I do not 
know if windows & mac get it also)

No problem to render portfolio of 3.7beta 40 on linux.

The readme is on my windows installtion (version 3.6). It also says at the top
of c_colors.pov

// Desc: Render via colors.ini,
//       generates html files and images for all the
//       colors in colors.inc

Those must be used as an animation from the corresponding *.ini files.
Outside an animation, the internal variable frame_number is valued as zero.
