Hi, Ok, osgprecipitation lz.osg works. So, I looked into the code and see it set the attribute and mode with the osg::Fog from the precipitation instead of just enable the GL_FOG mode and let the precipitationEffect do its work itself. I correct my program and it run yet! Thanks a lot Robert!
Now, I think it is normal to obtain undefined result if I enable fog without set the other attributes... But I still ask me why it worked until yesterday, since I introduced precipitation two weeks ago! "Les voies du seigneur sont impénétrables..."
