It is not the alpha nore diffuse confuse. I guess that my osx-ati-radeon-system does not handle what recent code does in SimGear with overriding OpenGL color etc. Just for my understanding: Is this new in FG to link and handle some of the effects directly via SimGear? (I am willing to own that I do not understand most part of this hack - its just because I never thought that I have to look into SimGear to find Effects/material-diffuse i.e.). Unfortunately I have to disable the "programs" in terrain-default/model-default/material-off/material-diffuse.eff at the moment - all the rest seems to work (osx 10.5.8, ati/radeon x1600, osg 2.9.8!).
