Well OK ... I'm good with the uv_vectors section. The values are an
index from 0 to 1 ... lol found that in the docs ;-)
According to the docs on the indices section ... "If the number of
normals equals the number of vertices then the normal_indices section is
optional and the indexes from the face_indices section are used instead.
Likewise for the uv_indices section." ... So it seems that /required/
section is face_indices. The only hint in docs about the values is that
hey are zero based .... but what about the two other values, not a clue
/yet/!
