Quite hard, the inital 8 angle shots for the movement of a sword would be moderately hard in 3dsm, becuase u would just have to design, set the mvoment render the output to all the seprate BMP's then imoport for each angle (which would be acheive by rotating the image 45 degrees each time)
However then you have to think about the mvoements for spells, skills, when u swing across your body (like when u hold shift_ the movement of the sword when you die and so on.
Do something easier. LIke make a spell in 3dsm, a spell like firebang, thunderstrom could be made fantastic if you had the skill and time.
