Many people are interested only in texture-changing MAT files, and it sounds like either will do the job, John's sounds a little more user-friendly. If you want to do more with PZ2 files, you will need a text editor and a bunch of tutorials, or CR2Edit, which will make PZ2 files for CR2, PZ3, PP2,etc files. MAT with the ability to set colors for each material (for texcolor, ambient, hilite), set all colors to white, include tex and/or trans maps or not, make Scaling MAT files, subdividing MAT files (of two types), JNT MAT files (joint parameter altering), and MOR files. (Current CR2Edit users, if your copy doesn't include all of these you need to check Help/Check Current Version) regards, Dan http://www.zenwareonline.com/cr2edit/cr2edit.html Sorry Win only for software http://www.zenwareonline.com for ZenPaint, ZenTile, ZenGrid and VueMaster
