Nvidia "A New Dawn" tech demo .NPK
Posted: Fri Apr 19, 2013 12:00 pm
Last summer Nvidia released remake of the old Dawn demo - "A New Dawn"
Resources in .NPK archives, so I wrote bms script to unpack them:
Unfortunately, I have an ATI video card and can't run the demo to tell if it runs with resources unpacked.
Models are still in NMB files (there are several topics on them on this forum), but format is different - all 3d data (verts, idx, normals, uv, etc) is divided to several files. These files are in models\geo_main.npk and there are also several NMB and NMA files in demo.npk, which, I believe, the main ones, that referred to the first.
My first experience in writing Noesis script (and second ever in reversing 3d model format
)
It imports vertex coordinates, normals and indices, no textures or even uv coords yet.
If someone can make a complete importer that would be great

IDString "\xBE\xEF\xCA\xFE"
Get FILES long
For I = 0 < FILES
Get FNAMELEN long
GetDString FNAME FNAMELEN
Get UNKNOWN longlong # UNIX/C date+time ?
Get FOFFSET longlong # file offset

Get FUSIZE longlong # file uncompressed size
FileXOR "\x62\x6F\x67\x6F\x6D\x6F\x6A\x6F" FOFFSET # "bogomojo"
