Stephen, (sorry I refereed to you as Alain last post...  misread the post in my
haste earlier!).

Your suggestion works great with these changes:
 Input_File_Name = animate_00000.pov
 Output_File_Name = animate_00000.bmp
 Initial_Frame = 0
 Final_Frame = 999999
 Subset_Start_Frame = 0
 Subset_End_Frame = 20501

However, the output files aren't (for example) animate_00000.bmp its
animate_0000000.bmp... seems to be adding zeros to the front (2 I think a I just
did a test with 10 files... I'm guessing if I set it up for the entire
simulation it will add 5 zeros). Is there someway to have it not add padding
zeros (as they are not needed since the input files are already labelled
accordingly).

Thanks again for your help,

Peter

Not the worst thing that I have been called. ;-)

The only way that I know of is to reduce the number of digits in 
Final_Frame.
I would be more concerned about using BMP files with the number of 
frames that you are using. BMPs are uncompressed and you will eat a lot 
of HDD space. Why not try PNGs?
Output_File_Type = N

And don't forget to use Continue_Trace=1
In case your machine crashes or you stop the render partway through the 
animation.

Only too pleased to pay back some of the help I've had over the years. :-D

The number of digit is imposed by the value of final_frame. If it have 6 
digits, then the files names will end with 6 digits.

Normaly, I never set final_frame to a large and use a subset. Only 
setting the final_frame value normaly works very well.

Simply using +kff20500 or +kff20501 on the command line start the 
animation for the desired number of frames.

BMPs are huge for nothing as they are not compressed in any way. It's 
highly recomended to set the output format to PNG. Use +fn in an ini 
file or the command line, or way beter, upgrade to version 3.7RC whitch 
default to PNG on all platforms.

Hi Stephen,

   After running through the simulations this way I discovered that with this
set up the first frame is just rendered 20501 times under sequential filenames.
For example it doesn't seem to load animate_00001.pov after finishing
animate_00000.pov, it just outputs animate_00000.bmp (from the first render) and
animate_00001.bmp (as the "second frame").. however both images are identical.
If I render 00000 and 00001 using the individual pov files (not using the
animation option in an ini file) the rendered BMPs are different (as they should
be).

Thoughts?

Peter

P.S. - For now, I've gone back to my batch file, but it takes much longer as it
(one at a time) opens the pov file, renders it, closes pov-ray, opens the next
pov file, renders it, closes the window, etc ,etc.

My first though is take more water with it. (Speaking personally, of 
course :-) )

Make sure that you are using frame_number, not clock. (Less calculations 
for you.)

Find out what is happening by using #debug.
Output your frame_number, the called include file and the object, in the 
include file.
Maybe add a #debug "This is Include NNN \n" to the first few files to 
make sure that they are being called by your master file.

 From there we start fault finding.
