MAJOR DIFFERENCE BETWEEN 3D MODELS AND 2D TEXTURES

I got asked for help on this topic so here goes. I hope I explain it well enough.


3D and 2D has their own particular meaning. 
      3D has 3 dimensional. In other words there are 3 directions, Vertical, Horizontal and Axial
      2D has only 2 Dimensions, Vertical and Horizontal

This is the major point with texturing Models in any program like iClone
Models made in tools such as Blender are 3 Dimensional.........X,Y,Z
75% of original size (was 671x19) - Click to enlarge

But making textures in tools such as Paint.net are only 2 dimensional..........….X,Y
75% of original size (was 671x19) - Click to enlarge


So, in order to enable a 2D image to get added to a 3D model the person who makes the model must add a UV map to it. It is the UV map that enables a 2D image to get loaded onto the 3D model and it is the UV map that controls where the 2D texture parts get added onto the 3D model. The primary point is, the UV map can only be created by the person who made the model. People using the model in programs like iClone can not change the UV map. They can only use the UV map made by the person who made the model to see where they need to put their images in their 2D texture so things show up on the 3D model in the right place.
