I did it! I created this pumpkin model all by myself — using Hexagon. And then figured out how to UV map it and set it up in Poser to load.
Only the pumpkin is self-loading, but I have included the transparency map to create a jack-o-lantern face.
I am going to write a tutorial on how to create the transparency map for the file, so that others can make their own jack-o faces. Kind of like a carving contest lol.¬† Note:¬† Transparency Map Tutorial can be found here.
