#This script takes the UV coordinates from a 3d OBJ model, and traces the faces of the model onto the UV plane with paths
#So you can get vector masks for your UVs!

#set the name of your file here, and the size your gonna want the texture
#then launch the script!
#note: when in fireworks, dont forget to combine paths to a union!
