My mesh2 file looks like this :
mesh2
{
vertex_vectors
{
n+1,
<x0, y0, z0>,
...
<xn, yn, zn>
}
normal_vectors
{
n+1,
<x0, y0, z0>,
...
<xn, yn, zn>
}
.....
scale <1, 10, 1> <----- QUESTION
}
I wonder if scale affect only vertex_vectors or both : vertex_vectors and
normal_vectors.
Tahnks in advance

It doesn't affect either. Transformations do not modify the mesh, they
just modify the incoming ray.

Hmmmm, it means that If I multiply by 10 in scale statement then during
rendering the postion of ray is divided by 10 ?

Not the position, the ray vector itself, but basically yes.

Ok, that was my way of thinking.
