im pretty bad at textures…
UV mapping eludes my grasp… i cant get my textures to the right places on my models ext…
but my textures are normally pretty crappy… so it dosn’t really matter…
but today i figured. why not try out making a texture…
after about an hour of trial and error i came up with this texture… all i can do is get it to wrap around the cube… or sphere… ext…
i thought it looked ok…
its supposed t be going for a guungy chipped paint / old beaten up robot or car look (or orks)
I had a lot of trouble figuring out UV mapping, too… here are a couple of things I found helpful:
You generally need to put seams on some of the edges. Imagine trying to unfold the model yourself if it was made of cardboard, and where the edges would have to be in order to unfold it until it was mostly flat. ( Mesh > Edges > Mark Seam ).
Use UVs > Scripts > Save UV Face Layout to output the outlines of your unwrapped mesh into a graphic file. In fact, you can start by loading that same file as your unwrapped texture, to see where the faces end up!
Hope this helps, and I think your beat up cube looks pretty cool! Try playing with the lighting, though; I usually use a three-point lighting rig for my test renders.

Is it merely a problem of unwrapping or rather of making the texture?
You also might want to try the new Smart Projections feature sometime, it makes pretty awesome unwraps of “simple” meshes automatically. Obviously it gives you less control to actually determine the UV Face layout but still, for simple textures it is quite nice.
Other than that, it’s all about practice, mechanical / blocky things are usually not that hard to unwrap with well placed seams, as sarah said (point 2 is also quite important, you will definitely need to export the Layout to be able to do a fitting texture in a 2D Editor!).
i know how to unwrap, export the targa file… and all that… i just cant get things like bump maps to work for UV mapping
i dont know how to UV project…
this was really just a test to see if i could do a bump map that looked good… but i cant get bump maps (made from normal maps) to work with UV… all i get is the normal map…
is there any way to have 2 UV maps on one object? cause thats what i really wanna know
Yes… you can have multiple unwrappings, and I think you can map multiple images to each… I remember someone (PapaSmurf?) talking about this in another thread not too long ago (which is where I first found out about it). You might find it with a quick forum search…
ive searched this fourm top to bottem… and i cant find anythign to help noobish old me
Hmm, well, let’s see…
In UV Face select mode, you can click the “New” button next to where it says “UV Texture” in the “Mesh” panel. That lets you make multiple unwrappings if you need them, I think.
To Map different images to different textures, I think you set the texture to be an image texture, set the mapping to “UV Mapping”, and put the name of the mapping into the “UV” Field near the mapping button.
I hope this helps… I haven’t tried it myself, though!
