Hello.

My problem is one discussed previously in some posts, but I put it on the table again because all previous posts were related to C++ plugins rather than coffee scripts inside C4D (9.52 in my case).
My question: Is it possible to access the normals via coffee (face or vertex normals?) . CreatePhongnormals(...) does not work within the Script Manager.
I would like to write an export plugin which respects the phong shading breaks and angle limits of the phong tag while exporting.

Thanks!

Man that's an old one. Anyway, maybe someone is interested into the solution here.
You can calculate the face-normals yourself

main(doc, op) {  
  var poly = op->GetPolygon(0);  
  var v1 = op->GetPoint(poly->a);  
  var v2 = op->GetPoint(poly->b);  
  var v3 = op->GetPoint(poly->c);  
  var v4 = op->GetPoint(poly->d);  
  var normal = vnorm(vcross(v3 - v1, v4 - v2));  
  println(normal);  
}

The vertex-normals are just the arithmetic middle between the face-normals of all ascending polygons.
