I am trying to set the object transparency from 1.0 -> 0.0 and vice versa;
but when I start changing the alpha of the material the object becomes dark.

I have changed the material parameters but without success; when I look in
the loaded model (for example cow.osg) for material, the material is always

I have modified the osgviewer example and attached it.

Could s.o. give me a hint what I am doing wrong ?
