Thanks Bobbie, went back to work with MPE, figured out the batch conversion and what it was doing. As far as I can now see, bump maps load in now the way they are suppose to. Some files won't convert, but I can deal with that now that the majority of them do :) It looks like I have some work cut out with converting, but will be well worth the sanity after lol. I do have 2 questions tho. First, for the MPE I read the tutorial and help files and understand that I can set the bump strength for default save. I tried the -100 (50%) as most here have said that it's a good strength in p5. However after converting, saving, and then applying the mat, the strength shows lower..something like 0.00342. Any suggestion on what number is a good number for the MPE strength default? Secondly, after finally figuring this all out lol, I noticed that my newly converted files are SO much larger than the p4 files. Is this normal? they go from around 4k to 100k. If it's norm, ok. I just want to make sure that I'm not doing some silly thing that uses up extra space and can be avoided. Thanks so much guys for all the help (and patience)!! P5 is definitely a whole new world! I know a year from now (hopefully sooner lol) I'll question myself as to why I hadn't upgraded sooner..but for right now we are having a love-hate relationship haha. I know after I get over this bump hurdle, I can go back to the breath-taking "wows" ;) Lady Stormy
