JMonkey Schatten werden durch Terrain hindurch angezeigt

[lord239123]

Hallo Leute,

wie ihr unten im Screenshot sehen könnt, werden die Schatten der Bäume im Hintergrund durch das Terrain hindurch angezeigt, obwohl sie eigentlich nicht sichtbar sein dürften.
Ich verwende zum Anzeigen der Schatten einen DirectionalLightShadowRenderer, welchem ein DirectionalLight hinzugefügt wurde.
Außerdem wird ein AmbientLight verwendet.




Die Klasse Map erbt von Node und enthält alle Spatials, welche zu sehen sind.
Im Konstruktor public Map(TerrainQuad terrain, String name) wird der ShadowMode für das Terrain festgelegt und in der Methode initTrees wird der ShadowMode für die Bäume festgelegt.

Hoffentlich kann mir einer von euch bei dem Problem helfen.
Danke schon mal im Vorraus.
