I am just starting out in Povray and have a question/problem. I got down to
hfdemo.pov and got an error: Error opening TGA image. I have looked in help
under TGA but cannot find any references to this problem.

Source:
#include "colors.inc"

   camera{
    location <0, 2, -10>
    look_at 0
    angle 30
   }

   light_source{ <1000,1000,-1000> White }

   height_field {
    tga "image.tga"
    smooth
    pigment { White }
    translate <-.5, -.5, -.5>
    scale <17, 1.75, 17>
    }

O/S: Win95, Pentium 2, 64 MB RAM, 6.4 GB Disk (half used)
Vers 3.1a for Win/NT

I am assuming the image.tga is a temp file created in the default image
directory. I don't think this can possibly be a permission issue. Can
someone please give me clue?

Thanks in advance

Have you read the docs?  You should change the "image.tga" into the name of
the image you want to use as a heightmap for the heightfield.  It looks like
you don't know this, but TGA is just a shortcut for Targa.  It's a file
format for images with up to 24 bits of colors (16777216 colors).  That's
one of the many image formats POV-Ray can read.  Just chearching to TGA as a
keyword won't give you results.
For a newbie, it might be useful to first read the entire docs.  If you
don't understand a part, just skip it until you need it.  (At least that's
how I've learned to use the POVRay description language.)

Hope this helps
