# Warning if the vertex order or vertex count differs from the
|
|
# origonal model the mdd was Baked out from their will be Strange
|
|
# behavior
|
|
#
|
|
# vertex animation to ShapeKeys with ipo and gives the frame a value of 1.0

|
# A modifier to read mdd files would be Ideal but thats for another day :)
