Injection Magic will work with the DAZ Generation 4 models, however it is a rather cumbersome program to get good results the first time.  But it does work. 

There are other programs, some free, that will spawn those morphs for you and create the INJ/REM files.  For textures, you would be better off creating MC6 files in the material room for distribution.  The MATPose files are hacks which were invented versions ago; they are slowly being replaced by material room files as it should be.
