Un compañero me ha pasado este script para la creacion de un manipulador para el softselection, es bastante comodo pero no me gusta su forma de gizmo esferico. A mi me gustaria que fuera un circulo que siempre tuviera la misma forma en todas las camaras. No se como hacerlo, evidentemente, y me gustaria que los expertos le echaran un ojo para saber si es posible hacerlo.

Gracias.

Saludetes.
