Sono di fretta ma posto questo script che ho fatto in python per estrarre in un colpo solo tutti i canali da un file VRIMG. Per ora è lanciato tramite un batch perchè non sono ferratissimo in python e avevo necessità di farlo funzionare, sono aperto a qualunque miglioramento :)Funziona da interfaccia per vrimg2exr.exe, ora sono proprio di corsa ma posto il codice perchè lo sto usando in questo momento e lavora da dio.
vrconv.bat:
@echo off
rem VRCONV: automatize vrimg conversion to exr,
rem finding all channels and separing them
rem -------- (C) 2011 Pietro Grandi -----------
rem Put here your ../vrimg2exr.exe complete path to find it

rem Requiring info

if errorlevel 1 (goto:error)
rem Generate info file
set VRCONV_FILE=%1.INFO.txt
echo cmd: File has been saved as %VRCONV_FILE%
python vrconv.py %VRCONV_FILE%
goto:eof
:error
echo Some error occurred with %VRAY2EXR%
