Hello, This tutorial will save you a lot of time, and possibly some money. If you have Qubicle construct, you can export OBJ files that are nice and water tight. Do not use the Qubicle Unity plugin, it does not export water-tight meshes. http://www.minddesk.com/vanilla/ind...n-models-with-qubicle-unite-in-unity-#Item_26 You need to import the mesh into blender. Press Tab to put it into edit mode. Select an edge on the very corner of you mesh and Press Shift-G and select face angles. Press shift-e and mark seam. Select a texture for your UV map, and press the BAKE button to bake your textures to the UV map. That is it! You now should save your texture, and blender file. You are now ready to drag-and-drop the blender file onto unity.
