MeshNormalSmooth() takes a vertex and iterates all the others, looking for vertices with a distance < epsilon.
Then it calculates their normals and sums it.

That's not a good idea, IMO:

• Two close vertices can be not physically linked, I don't think summing normals makes sense.
• It's quadratic.

A simpler and faster way to smooth a model could be:

• Iterating through each triangle
