I made a free app that convert P4 MAT pose to P6 MAT. Depending on what you are doing, there is also a "Material Mixer" module, that allows you to change the texture in any existing MAT pose (or any Poser file) by a simple drag and drop feature. Finally, you can use the Material collection feature, then open it in a text editor and change the line "mtlcollection" to "figure". You will also need to change the extension (from *.mc6 to *.pz2). But i must admit i don't know how well a Poser6 MAT file is applied in Poser5. This can also be done automatically by my app. PS. It's working with the framework 1.1, ie on WinXP. PS2. The app is still in Beta... So make a backup before doing the changes !
