I am trying to put a new unit skin and animation (http://forums.civfanatics.com/downloads.php?do=file&id=10951) for a nuclear bomber into my mod, but almost every time I try to put a unit skin into a mod, I am confronted with about twenty different files, so I do not know which files to use. Is there a trick to finding and using the right files, or do I just need to ask the maker every time?
