Greetings -
I am trying to find out the file format for NDL's "NetImmerse File
Format, Version 4.2.1.0", really just version 4.2. This "nif" file
contains polygon information for a graphics/physics engine. I am
looking for a specification with a similar look/feel as this:
http://home.cinci.rr.com/jimadam/MorrowindESPFormat.html. (This
document has a reference mechanism to other .nif files)

The end result of what I'm looking for is byte offsets, and
root/child/node information. Please let me know if you need more
clarification.

Hi buliwyf-ga,
   Unfortunately, the NetImmerse file format is a proprietery format
whose contents are a closely guarded secret. It appears that companies
that license or buy this engine do not have the right to release its
code. Also, the companies that license the engine can extend the file
format by adding custom object classes to it. This means that even if
you knew the default NetImmerse file format, you would still not be
able to make sense of the nif files shipping with a particular game
unless you knew what modifications had been made to it.

You can of course, license the NetImmerse SDK or download the free
plugins they have for Maya and 3D Studio Max from

Hope this helps.

Yea, I found that too.. I was hoping a researcher could find something
I could not. :) Rev-engineering 3.x was a pain, and 4.x seems to be
10x as much a pain.
