is anyone have some info about diff between q3 file format bsp and MD3 and those in RTCW format, and how about new model format like MDC or MDS is there some tech info around ? Struct of RTCW bsp seems not be the same as i try with some q3 level viewer ( which run fine with any q3 bsp file )

the SDK will be released soon, Im sure they will also release information on the file specs as well.
