Here's wikipedia article:
http://en.wikipedia.org/wiki/UV_mapping

My short (not so good) explanation:
When texturing a mesh (covering its 3D surface with a 2D image), you always want to wrap the texture around the mesh in a certain way. UV coordinates are the parameters that define the position, orienation and size of the texture for each particular face of the mesh.

When I use UVMapper then Photoshop to add textures to circular or coned shapes I get white lines at the joints. (As per pic of the cone below)
Does anyone now why? and how do I stop this from happening?



Thanks.

Making the texture go over the edge in photoshop will probably sholve this problem. Now you probably forgot to texture one line of pixels, which leads to this edge. Just make the the texture a little bigger then the mapped cone.

Try this:  Create the texture you want, in this case red and white stripes and dirty blotches, in whatever graphics software you have.  Now, Illustrator and Corel do this automatically, but you might have to do it manually.  Basically you want to split the image into four corners, and swap them diagonally.  Now the image will wrap neatly, the left side lining up perfectly with the right side, but of course you will have an uneven cross shape through the middle of the image.  Use smudge, blend or clone tools to fix this up and voila, you have an image that can tile indefinitely with no discernable line between tiles.  I can do a bit of a tutorial on this if anyone is interested and this isn't clear enough.

Spicy: Adobe Photoshop Elements 6
ENSONIQ5: A tut would be great

For info, I've started a folder containing loads of useful items like:
Cones, pallets, barrels, barriers and skips etc, which I plan to post on here somehow so anyone can use them for free.

Just need to perfect the texturing now.
Thanks

that's a great idea, needless to say i made a "scenery and stuff" folder about a week ago, i've got about 8 subfolders and i think it's a great idea for any anim8or who doesn't want to spend hours looking in all your anim8or files for an object you've already made

(basicly, make a folder with a load of objects which you can re-use)
