**Hi ThrommArcadia,
**I Understand what youre saying.
The template i use in 3dsmax is 4096/4096 ,like u said :Your template layout there would have to be a lot huger then Poser's resources could handle to give the same pixel width on the face alone
I can do this because Max instanced the bitmap.
For poser i'm trying to split-up the bitmap's because like you said:A bunch of 4096X4096 textures would send Poser 6 and lower into a nose dive
Poser uses the same bitmap {for example "Body"} about 15 times to cover up the mesh because of several matregions right?
What if this could be split-up , by that i mean for example the fingernails require the complete bodytexture bitmap right ? 
If you would split the texturemap and give poser only the nail's portion of the map?
I'm a making sense ?
