Queri It's an 800MHz Combo iBook, 640MB RAM running 10.2.6. wgischick Just keep your existing Poser 4 installation with its runtime. You will be able to use the runtime from Poser 5 and just in case something doesn't work in Poser 5 the way you know it from Poser 4 you have the option of using the older version. No need to reinstall or move any files. CrystalDragonSorry, the material room is not yet exposed to Poser Python.
