i was playing around with this mod the other day and i think we need to use the C function interface instead of defining the Types inside of the Extern. the method parameters that are required arent easily done in BMAX whereas the C function interface is better in that respect. still, i did some initial testing and could not get the callback functionality to work... just kept getting internal errors. if someone else doesnt look at it before i get to it, i may give it another whirl.
