Trying to create a mesh for use with meshcam and I'm struggling a bit 
because when I use uv_mapping with the povray procedural texture it 
looks wrong ... comment it out and it's all good. I'm thinking something 
isn't right with the uv_vectors portion. The mesh was created in 
blender, exported as .obj because .3ds didn't pick up the uv map ... 
then through poseray to pov mesh2 format.

I understand what's going on with the vertex and normal sections, can 
someone add some clarity to the uv section? As a guess, since there are 
only two faces, the remaining sections are talking about those.

mesh2 {
   vertex_vectors { 4,
     <9.5,0,9.5>,
     <-9.5,0,9.5>,
     <-9.5,0,-9.5>,
     <9.5,0,-9.5>
     }
   normal_vectors { 4,
     <0,1,0>,
     <0,1,0>,
     <0,1,0>,
     <0,1,0>
     }
   uv_vectors { 4,
     <0,0>,
     <1,0>,
     <1,1>,
     <0,1>
     }
   face_indices { 2,
     <0,1,2>,
     <0,2,3>
     }
   uv_indices { 2,
     <0,1,2>,
     <0,2,3>
     }
   normal_indices { 2,
     <0,1,2>,
     <0,2,3>
     }
   inside_vector <0,0,1>
   }

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/!
