Export fail. Main string ARGS error.
Found one solution for that. Some stuff errors out on that code, very annoying.
I was trying to get the Alpha A90 ekranoplan
converted, kept getting that error code.
I traced it back to texture names with non letter characters in the the name. In particular, MCX does not like ampersand (&) in the texture titles.
Doesn't seem to bother dynamic VC panel tex's, though.
If you are getting that error on export, rename any textures with & @ # $ % + or what ever.
Won't help with the 68K vertice error, though.
