UVW map stores texture coordinates
UVW map is array of vertices. Each model triangle have a three corresponding vertices on UVW map, storing texture coordinate.
Normalization
Texture coordinates are normalized to the image size, in other words they are independent from texture resolution. In Blood Omnicide, up left corner of texture is always (0, 0) and right bottom is (1, 1). A values greater than 1 or lesser than 0 causes texture to be repeated.
Usage
Texture coordinates are used on mesh models and patch meshed.
Brushes dont use texture coordinates, they are using special technique to generate texture coordinates called texture projection.
