Since different people asked for the MTL extender over the years and since I couldn't find it here at any place, I decided to upload it again

That provided archive is from 2005 and unfortunately doesn't contain a readme.
That's why I'll give a short description.

INSTALLATION

    Copy DXMTLDummy.u and MTLExtender.exe in the system folder of DeusEx
    Add DXMTLDummy to the list of EditPackages (in DeusEx.ini) ABOVE your own mod

USAGE

    Compile your mod with UCC
    Execute MTLExtender.exe
    The program will ask for the desired file to be MTL extended; specify your mod with extension (e.g. SG_MOD152.u)
    After pressing ENTER the program will automatically change the binding from DXMTLDummy to DXMTL152b1



If you compile your mod using a batch processing file, you can also specify your mod as first commandline parameter to the MTLExtender.

e.g. MTLExtender.exe SG_MOD152.u


That's all I can remember so far.
