Texture Map file types

[Rustle32]

I have been messing around with modding and am attempting to replace or create some textures. I'm new at this, tried searching around but could not find a description of the different types of .dds files with an underscore suffix in the name.

 

I have figured out these:

 

• 
  _n = normals or bump map
  _g = glow or luminance
  

 

but there are others I'm having trouble figuring out their purpose.

 

Here is a list of some of the suffixes I've seen, mostly in order of frequency seen:

Suffix - - - Example file

• 
  _m . .. ceremonialblade_m.dds
  _e . . . bleakfallscube_e.dds
  _p . . . wrstonebase02_p.dds or mineore01_p.dds
  _d . . . dark brotherhood robe_torso_d.dds or dagger_d.dds
  _s . . . grayfoxbust_s.dds
  _b . . . icewraith_b.dds or wolf_b.dds
  _em .. ironmace_em.dds
  _rim .. psiijicrobes_rim.dds
  

 

If someone could point me to a list of the texture map modifier definitions, or help fill out the list here, it would be most appreciated. I would like to understand these map types to create better textures.
