Hallo,
ich versuche gerade, das Papervision Beispiel der rotierenden Erdkugel nachzubauen:

Allerdings bekomme ich immer die Fehlermeldung:
TypeError: Error #1007: Versuchte Instanziierung für einen Nicht-Konstruktor.
at StaticPapervisionGlobe()
Das Script habe ich fast ausnahmslos aus dem Tutorial verwendet:
Woran könnte das liegen?
