Kristta: To make the correct paths in your zip files, make a dummy Runtime folder, for instance on your desktop. In that, you create the folders needed (of it's textures with Mat poses you only need RuntimetexturesKristta and RuntimelibrariesposeKristta (of course WHAT you call the final folder is optional) Then when you're done, assuming you've got winzip installed (who hasn't?) simply rightclick on the Runtime folder you made and from the menu chose "Add to runtime.zip". That will give you a correctly path'ed zip called Runtime.zip. You can then rename it to whatever you like. This is the fastest way. To make the thumbnails: Render a 91x91 picture of whatever you want to make a thumbnail for and save it as a png. Be sure to name it the same as the Mat pose (or whatever) - you can then use P3DO Explorer to make an rsr file from the png if you want. That way it's compatible with P4 without Pro Pack as well :o)
