[osg-users] osgshadowd.exe = black

[Adrian Egli OpenSceneGraph (3D)]

Hi,

what texture the osg viewer is looking for, may this black shadows are
coming form the "dummy" texture trick we integrated into all shadows
technique (shaders). can you please check out, wether it works when the
texture are found. OSG_NOTIFY_LEVEL=DEBUG may helps.
