Using a Mac with OSX I've had a problem with two obj-files: the House-Mouse from DAZ and Jessi in Poser 6. The obj-files of the House Mouse are different between Mac and PC, IIRC there are extra line-feeds in the Mac version and that is enough to prevent RTEJava from working. As I have a PC also I tried to decode the stuff with RTEEncoder and it didn't work either. I don't remember exactly what the problem was with Jessi, but I think it was that the time-stamp is different between the Mac and PC versions, and that RTEEncoder didn't work here either with the Mac version of Jessi. Edited to add that no, I wouldn't hesitate as long as I am sure I have the correct source-file.
