| UV Mapping & Texturing Tutorial Author - BigTallBill (http://bigtallbill.deviantart.com/) |
In this tutorial you will learn how to make a UV map of an object you wish to
texture using Blender's 'seams' functionality. By learning how to do this
correctly you can apply effective detailed textures to almost any object,
ushering your work into a new level of complexity and flexibility.
Note: You will need blender v2.34 (or greater), and an image editing program like
Gimp or
Photoshop to
attempt this tutorial.

Step 1 - Start Blender and add a cube of an appropriate size. Now switch to top view (Num Pad 7) and extrude the cube in the exact same way as the image to the left. If you do not know how to use extrude, you may wish to view Blender's documentation before you proceed... ;) |

Step 2 -
Exit edit mode and press F to enter face select mode.
Split the main viewport in half and change the new view to the UV/Image
Editor window. |

Step 3 -
Select all the faces and click UV > LSCM Unwrap. You'll notice in the UV window
that the Vertices are all messed up, and the faces aren't visible. To
correct this we will have to make use of seams. |

Step 5 - If you have done everything correctly, you should have a UV map resembling the one opposite. |

Step 6 - Now in the UV window rotate the edges so that they are straight. Then resize the windows and zoom in until the UV map fills your screen. Take a screenshot by pressing PrintScrn on your keyboard (next to Scroll Lock). *OR* as an alternative, select UVs > Save UV Face Layout, and let Blender save it as a .tga. |

Step 8 - Restore your windows to normal and go to Image > Open in the UV window's menu. Select the image you saved in step 7 and move/resize it until it superimposes over the existing UV map perfectly. |

Step 9 -
In the main window switch to Textured mode to allow you to see your
finished pre-rendered object with the texture applied. |

Conclusion - And here is our final result! Now that you know which number corresponds to each face you can, of course, do more detailed texturing work... but I'll leave that up to you! Try practising with more advanced shapes to exercise your 3d mind further, and perfect your UV mapping technique. Have fun! :) |
