I finally got P5. Looks good, works just fine, not a hang in sight, using SR2.1 of course. First thing I did was to copy the entire contents of my P4 Runtime to P5, I don't want to do external connections, I want it to function perfectly - V3 INJ, textures and all that. I got it to work in the end. (I have the P5 install on a new, separate disk) Now my qestion to the P4-P5 experts is: What should I watch out for? What should I avoid? Are there situations where a P4 file is not going to work in P5, or some contents of the Librariea folder, or bumps or anything else? What do I need to know to not get trouble as I move over to P5? For instance, does P5 understand Bum files or do I have to create jpg somehow? My P4 cr2's and Pz3's seem to load and render just fine so far in P5. What I do know is that a P5 file may not necessarily work in P4. Nodes and stuff like that are added so PZ3's are not backwards compatible. But that's OK. Hopefully I can do a permanent migration. Are cr2's and other file types also not backwards compatible? :] Fish
