I have an understanding of the Whm in FFE: tutorial - Dawn of War - Adeptus Modificatus

PT.1:
File name is up the top. :)

SSHR is the texture link.
TXTR is an internal texture.. Not listed. :)

SKEL is where the bones are. :)

MSGR/MSLC is where the objects are. :)
MSGR/MSLC-data is where the object data is. :)

PT.2:
File name up the top again.

MARK is where the markers/helpers are noted.

ANIM is the location of animation files.
ANIM-data is where the information about the animation is. :)

* MSGR-data Contains a list of the objects(MSGR/MSLC) in the MSGR(ref).

With editing these in file format editor, check links with other parts of the file as you could end up with Pink Bawkses too. :)

Enjoy.... :)
