Here is how mine starts:

{

version
{
number 8
}
mtlCollection
{
material 4_InnerMouth
{

 

I will edit to:

{

version
{
number 8
}
figure
{
material 4_InnerMouth
{

 

Save as pz2, copy over the png file.  Opened Poser and nothing.  It recognizes the file supposedly, I don't get that 'warning'... but it also doesn't load my pz2/skin mat.

How do I know if they are "compressed files"?  When I look at the file type in the materials folder, it says "mc6" so I'm assuming it's not.  I'm starting to see why Sam just applies his mats in the materials room... sheesh.  I just thought putting it in the pose folder would allow me one-click access, quick and easy.  not so quick, and not so easy.
