if you build your max scene in max units, then 1 max unit = 1 blitz unit. then the simplest way to get your character where you want it is to position your level in max so 0,0,0 world coordinates is where you want your character to appear. then load your mesh in blitz at 0,0,0 and it will be i that exact spot. remember to move the pivot for your character object to its base, or offset the character in blitz or it may end up being half way through the floor.
Thats the simplest method thar requires almost no coding at all.
