# mdd importer by Bill L.Nieuwendorp

# conversion to blender 2.5: Ivo Grigull (loolarge)

|
|
# 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 :)
