I've NEVER textured something before with all this UV talk.. I'm just confused about what they are.. and if anyone knows of any beginner (very easy.. ) tutorials, that would be great.

I recently started modeling with poly's, so now I'm starting to pray regarding texturing haha

I'll try to answer this with an example.

You have a globe and a world map. The globe will be your object and the world map is your texture map.

On the globe you can find LA or NYC as a point so it has x,y,z coordinate, then if you look at your map you will also find that city too but it will describe as longitude and latitude, this is the U and V value.

In terms of UV mapping, U and V coordinate is a point position in texture space not in euler space.

So a point in your model will have x,y, and z coordinate in euler space, and will have U and V coordinate in texture space.

Does it help?

It helps very much thank you :)

I just need to know a general procedure on how to texture, very simplified with dumbified terms for someone like me. I have no clue where to begin.
