Just to make life a bit easier - it seems (been experimenting lately) that all you need is what you actually want to change. With a MAT pose adding a tex, all you want to change is one thing in the figure section. The text below is a complete MAT file, and it works (yeah, I'm surprised, too). Curly bracket at the beginning and the end seem to be necessary to tell Poser this is a Poser-relevant file : { figure { material Tunic { textureMap ":Runtime:textures:PoserStyle:MikeImmortal:ImmTunic1.jpg" 0 0 } } } In the same vein, I've reduced the default material settings in my home-brewed CR2s to something like this : material Tunic { KdColor 1 1 1 1 KaColor 0 0 0 1 KsColor 0 0 0 1 TextureColor 1 1 1 1 } material Belt { KdColor 1 1 1 1 KaColor 0 0 0 1 KsColor 0 0 0 1 TextureColor 1 1 1 1 } material Preview { KdColor 1 1 1 1 KaColor 0 0 0 1 KsColor 0 0 0 1 TextureColor 1 1 1 1 } Poser seems to default the rest. Quite a forgiving program ;o)
