    Yo tengo un terreno muy grande, dividido en partes pequeñas. Lo que hago es activar y desactivar el GameObject de la escena para optimizar y me pasa exactamente lo mismo, me salen esos picos pero con unity 2017.3.1f1, lo tengo con unity 5.6.3 y no tengo ese problema.
    Cómo podria solucionarlo?
