[Sharing] Distribute PVRTexTool commands for faster texture converting

PowerVR Insider

Hello all,



My projects often contain hundreds/thousands textures so it takes a lot of time to convert them all to compressed formats.



Therefore I wrote a tool called win2tiz and would like to share with you: https://drive.google.com/open?id=0B1bLtkV8mMk6b2tySndDMlhsN0U&authuser=0



This tool will help you execute commands faster by distributing the commands to dedicated servers.



Current supported commands:


  • PVRTexTool.exe (old version)
  • PVRTexTool34.exe (new version)
  • etcpack.exe (note that currently etcpack.exe itself cannot runs parallel due to the conflict of temporary files, waiting for ARM Mali to fix this)
  • GCC/G++ compile commands



    REQUIREMENTS


  • Windows 7, 8, 10 (not tested on XP)
  • .NET Framework 3.5+



    HOW TO USE



    1. Setup your dedicated severs:


  • Copy the folder win2tiz to each server, the path should be short and MUST NOT contain spaces (e.g C:win2tiz)
  • Copy your tool (e.g. PVRTexTool) to a identical path (e.g. Y:/PVRTexTool/PVRTexTool.exe) for all severs
  • In each server, start the service by running: mongcc.exe --start -port number

    For example: mongcc.exe --start -port 1909



    2. Clients distribute commands:


  • In each client, set following environment variables (example):

    set MONGCC_ENABLE=1 // if set to 0, then all commands will be executed locally, no need servers

    set MONGCC_MAX_JOBS=4 // how many commands will be executed parallel, typical 4

    set MONGCC_HOSTS=servername1 servername2 servername3 // computer names of the servers, separated by spaces

    set MONGCC_PORT=1909 // the port number, must be matched with the one on servers


  • In each client, export all your commands to a text file, each command is on a line; then execute:

    win2tiz.exe --cmd -file yourtextfile -jobs number

    For example: win2tiz.exe --cmd -file D:myfile.txt -jobs 4



    This will distribute your commmands to the servers and receive the results, in a parallel way.

    The jobs number should not be greater than MONGCC_MAX_JOBS, otherwise you will get an error message.


  • An example of a text file that contains PVRTexTool commands:

    Y:/PVRTexTool/PVRTexTool.exe -fETC -iE:MyTexture1.tga -oE:MyTexture1.pvr

    Y:/PVRTexTool/PVRTexTool.exe -fETC -iE:MyTexture2.tga -oE:MyTexture2.pvr

    //Y:/PVRTexTool/PVRTexTool.exe -fETC -iE:MyTexture3.tga -oE:MyTexture3.pvr

    //Commands that are empty or begin with // will be ignored.



    NOTE


  • The path to the tool (Y:/PVRTexTool/PVRTexTool.exe) must be the same for all clients and servers.
  • If you are using new version of PVRTexTool, please rename it to PVRTexTool34.exe
