[SOLVED] Shadows depend on absolute scale of object?

[Scheikl]

Hi!
When scaling down an object (e.g. when you want to have your scene in meters instead of millimetres), shadows are not drawn on the objects anymore.

Scaled scene:

<?xml version="1.0"?>
<Node 	 name="root"  dt="0.02"  >
    <RequiredPlugin pluginName="SofaOpenglVisual"/>
    <RequiredPlugin pluginName="SofaGraphComponent"/>
    <RequiredPlugin pluginName='SofaLoader'/>

	<BackgroundSetting color="0.5 0.5 0.5" />
	<MeshOBJLoader name="meshLoader_0" filename="mesh/dragon.obj"  translation="0 0 -0.05"  scale3d="0.003 0.003 0.003" handleSeams="1" />
	<OglModel template="Vec3d" name="VisualModel" src="@meshLoader_0"  material="Default Diffuse 1 0 1 0 1 Ambient 1 0 0.2 0 1 Specular 0 0 1 0 1 Emissive 0 0 1 0 1 Shininess 0 45 No texture linked to the material No bump texture linked to the material "  blendEquation="GL_FUNC_ADD"  sfactor="GL_SRC_ALPHA"  dfactor="GL_ONE_MINUS_SRC_ALPHA" />

	<DirectionalLight name="spotLight1"  shadowTextureSize="512" direction="-0.5 -0.5 -0.5"  shadowFactor="1" />

Do you have an idea on how to address this issue?
