With vec_for_vertex you can get the relative position of a vertex. So is it true that 3 following numbers build a triangle (polygon)?

So this would give me the first triangle of the entity:
Code:

var vert1, vert2, vert3;

vec_for_vertex(vert1,1);
vec_for_vertex(vert2,2);
vec_for_vertex(vert3,3);



Or are the vertex numbers from MED like you build the modell (random)?

Thanks
