I am trying to load a long sequence of TGA files into this image map:
image_map { tga concat("D:\\sketches\\follow", str(clock*600,-4,0), ".tga")

in the folder Sketches folder on my D drive there are 1800 files starting 
with
follow0000.tga
to
follow1800.tga

Can someone see a problem with the string here? I want to read in only the 
first 600 while the clock moves from 0.1 to 1.
The whole code segment is:
#local D=
  pigment{
   image_map { tga concat("D:\\sketches\\follow", str(clock*600,-4,0), 
".tga")   //group.tga is excellent   1352
  map_type 2 interpolate 2 once } translate <0, 0,0> scale 1 + clock*2 }

and I am getting a Parse Error that says: Cannot open TGA image.
thanks much for any help.

This won't solve the problem, but will help you find out why it's not 
working:

#declare ImageName = concat("D:\\sketches\\follow", str(clock*600,-4,0), 
".tga");
#debug concat("Attempting to load ", ImageName, "\n")

image_map {
    tga ImageName
    //...
}

I haven't checked it, but if you send your "concat" statement to #debug, 
you can verify whether you're actually getting the correct string. 
However, since you're only wanting integers, I'd suggest using 
"frame_number" rather than "clock."  (Just the first thing that occurs 
to me; hope this helps.)

I thought it was "fools seldom differ"? :)

I'd use frame_number instead of clock like this:

  image_map { tga concat("D:\\sketches\\follow",str(frame_number,-4,0),".tga")

Do you have read permission for that folder? If you don't have read permission, 
you can't access the files if the I/O restrictions are active.
You may need to add a line like this to the "pvengine.ini" file from the \ini 
folder:
in the section [Permitted Input Paths]
3=D:\sketches

The number is to follow the last number in that section.

You didn't say what version or platform you are using there so this could be 
unrelated.
Giving it a try here POV for Windows 3.6.1c crashed, no error message. I 
have the current 3.7 beta "installed", not simply added to the 3.6 bin 
folder. I can run this (similar script) from the 3.7 beta, no errors. Using 
Vista here.

It has been a very long time since I did any animations using version 3.6 so 
I couldn't say if anything has changed.

I was just wondering about your 0.1 to 1 clock if you want the first half of 
images from 1800 total. Start image number would then be 60 not 0.
