THats a good idea dvdcdr. I've got Discreet Motion Builder myself.  Currently I'm trying to change victoria3 by getting rif of her buttock bones because hey present a problem in Motion builder. They behave like a sperate appendage from the rest of the legs in MB so when you animate a leg it splits at the seem between the two leg parts With  Sd3 boujouyou can export camera data for MAX, Combustion an few others and just a plain text file.
