Create the PIV-Ray.ini file SimpleAnimation.ini using notepad, and in this file specify the number of .pov files as Initial_Frame / Final_Frame . This .ini file is the file that you open and run to display all frames. You can also use Subset_Start_Frame / Subset_End_Frame with duplicate .ini files when rendering subsets across multiple machines:
Input_File_Name="SimpleAnimation.pov"
Width=800
Height=600
Antialias=On
Antialias_Threshold=0.05
Output_File_Type=N
Initial_Frame=1
Final_Frame=124
Subset_Start_Frame=1
Subset_End_Frame=124
Then your SimpleAnimation.pov file will be downloaded once per frame, and in this .pov file you simply load the desired frame file using the POV-Ray variable frame_number :
#if(frame_number=1)
#include "SimpleAnimation000001.pov"
#end
#if(frame_number=2)
#include "SimpleAnimation000002.pov"
#end
#if(frame_number=3)
#include "SimpleAnimation000003.pov"
#end
Input_File_Name SimpleAnimation.ini Final_Frame, 124 :
