LOL. Looks like I've become customer support fro the ProPack ;-) That's ok I don't mind the questions. But be aware. It's new for me too. So I might be wrong about certain things. So take what I say with a certain grain of salt. 1.) It looks like any file containing custom geometry will produce holes using the PP. So yes. That might effect your items you are selling. But at least if they are in the default pose. The more experienced users will be able to export all the extra's. And rebuild it while running the PP. be aware. I'm still testing things. I might be wrong 2.) It only adds additional sub folders to the Runtime folder to accomodate the new features. Like the Python addition. It does not seem th EDIT any of the other folders you are used to seeing there. 3.)Yes. It does automatically generate a .PNG file for all the figures you have in the library. But it does this by accessing the .obj file and the cr2 file. Not the .rsr. So it doesn't erase it. It leaves the thumbnail .rsr behind. So you can still use it if you need to. The neat thing about this new thumbnail system is that now everyone. Even me without having a graphics card capable of 32 bit graphics. Is able to generate those really nice looking thumnails that we all like. ScottA
