We need to use long path names for the md3 paths and more generally all entity 
keys. Probably need to check that there are no spaces in the files so we don't 
confuse the .map parser too. I still think it's better to maintain short file 
names in the project settings .. but we could try to turn that off too and see 
what happens.
