| - | * Examine any smooth edges you have cut durring the unwrapping in 3D application - now they appear hard in viewer! Select with a box each verticle of each of these edges and use "SHIFT+E" to view vertex properties. There are probably two verticles. Press Shift+D to merge them. After dooing the same for other vertices along the edge you can select them all (carefull not to select extra ones) and press I - to turn the edge they create into a soft one. You might have to select the model and hit F5 (recalculate normals) to see results. | + | * Examine any smooth edges you have cut during the unwrapping in 3D application - now they appear hard in viewer!
