have you tried setting "AxisOfRotation" to Vec3f::Null ? The code in
OSGBillboard.cpp looks like it handles that case and aligns it the way
you want. You can also use the test program testBillboardRender (in
Source/System/NodeCores/Groups/Misc) to play around with the different
settings by using the keys y,x,c,v,b,n.
Hope it helps,
Carsten
