First and foremost, backup the file "zombie/core/skinnedmodel/ModelManager.class". Put it somewhere safe. Next you'll need a model with texture in their appropriate "media" folders. I won't explain how to model for PZ here, but Jab's blender converter should help http://theindiestone.com/forums/index.php/topic/12864-blender-3d-model-import-export-scripts-274-wip/ Now find and download a utility which can view and edit Java bytecode. I use http://set.ee/jbe/ but there are definately others. Op
