IF YOU HAVE POSER PRO PACK YOU ACTUALLY CAN'T CHANGE THE .JPG TO .BUM. YOU NEED TO OPEN THE .CR2 (IF YOU ARE WORKING WITH A FIGURE) IN A TEXT EDITOR AN EXECUTE THE FUNION FIND .BUM AND REPLACE ALL OF THEM FOR .JPG( ONLY ON THE LINE THAT SAY BUMP_MAP). IF YOU HAVE NORMAL POSER THEN YOU NEED TO OPEN THE "RENDER MATERIALS" SUBMENU AND SELECT THE BUMP MAP INDIVIDUALLY, POSER WILL CONVERT .JPG TO BUM. CORRECT ME IF I'M WRONG...........( SEMI-NEWBIE ) (~_~)
