How do I make a texture fit a 3D model?

<< < (2/4) > >>

Blademan.Exe: UVmapping basically its a flattened jpg or png template of your model so I would recommend Roadkill if you want to do any texturing, though Anim8or`s built in Basic UV editor can be used Here is a tutorial I wrote some time ago now on the now defunct Anim8orworld.com

ROADKILL - Part 1
UV Flattened models



So lets start to uvmap and unfold a character. For the purposes of this tutorial we will use  a low poly character from BOB-I_Ts F8ce script. We have adjusted the model to suit the unwrapping process. Important: Roadkill uses .obj format models .an8 files will not work with this


You will a need a copy of Roadkill and Uvmapper , which you can get here....

Roadkill:
http://www.pullin-shapes.co.uk/page8.htm

UVMapper:
http://www.uvmapper.com/downloads.html

So Lets fire up Roadkill and load in the Model , use the Alt Key in conjunction with Left, Right and Middle mouse to move your model about in its window. Also in the switches menu check "Don`t Select Back Faces" and "Single Select".
This program will work fine for quad meshes, so we will start with the neck, move into the region, click on a horizontal edge then hold down the T key. The previously selected edge will turn yellow just keep your finger on the T Key and move around the neck selecting all the horizontal edges, Some ambidextrous use of your fingers will be necessary when moving around using the alt key and sometimes the Z key(Undo!!)
 The complete set of edges should be selected.



Now hit the C key and that selection will be cut, so effectively you have cut its head off!   
Let`s now unwrap the head, start at the back of the head then select in the same way the edges shown in the next Two screenshots




Then again use the C Key to cut the selection
Your UVmap should now look like this..


Now we are going to cut up the Arms, Hands, Legs and Feet in exactly the same way. Here is the result after the cuts.



We will cut the Torso down the middle.In the screenshot we have cut down the middle of the torso groin area and rump leaving the back intact.



We now go to the hands and feet which are a little more time consuming as we will need to go round selecting edges around each finger and toe.
See the images attached



and



Finally cut these using C and the cuts and unwraps are complete.

 Lets  turn our attention to the actual UVmap generated. Click in the UV window then zoom into the Face UV map. Now we go to UV mode Press U then double click on an edge on the outline Make sure that you click on an intersection otherwise it will not work see the screenshot below.



The yellow dot indicates an intersection, If you double click the intersection here the cut lines will be highlighted see below

Roadkill Pt 2

Lets pin these points down just press P and the UV will be pinned. The selected points will turn blue.
 We can now scale the facial features up to make them easier to texture later in the process. Press the U key, select all the edges in the facial features (if you hold down the shift key you are able to multiselect points, but bear in mind that multiselecting points already hightlighted will switch off!)



Now Press the R key and use the right mouse button to scale up the faces.
Once you are happy with your unwrapped template export the model using "Save As..."

He is now ready to be loaded into Uvmapper, so that we can extract the template. With the new obj loaded into UVmapper it is just a simple case of resaving the template and model. Again whilst in UVmapper, If you wish to resize or move the template parts then it is just a case of highlighting and moving scaling etc.

DO NOT FORGET to resave the Map AND MODEL if you do these operations, as the UV  co-ordinates will have changed.

Umm... Then how can it work with Anim8or?

neirao:
BladeMan, i use "Wing 3D" http://www.wings3d.com/
export .obj from anim8or, import in wings, create the image texture, re-import the obj. and the texture on anim8or

[/youtube]

Wings is Free too. But for modeling..easyly, ANIM8OR  IS VERY BEST!!!
 :D

BladeMan.EXE:
Okay, I just figured out how to make .obj files. I was hitting "Save as..." instead of Import.

Thanks.
