I've been trying to make a new object set for the last couple of days. I make the object in Blender, twist it and tweak it to the shape I want it to be, open it in UVmapper, save the UV map over the original OBJ file, then assemble everything in SimPE. When I put the new object in my game, it appears incorrectly, i.e. missing several faces. I don't understand why this is happening. When I save the object, I make sure all the vertices are selected or I save in object mode with the object selected. The same when I export the OBJ file to my project folder.
I've tried going back to blender, selecting the faces that don't appear correctly, erasing them and refilling them. That doesn't work either. It just screws up the UV map.
I don't know how to solve this issue. It's annoying to create and assemble an object with 3 or 4 texture maps and then not have it appear correctly. It seems like I'm doing everything correctly, most of my objects appear the way I assemble them. Is it a fluke or is there something I'm doing wrong?
