Re: [osg-users] osg rain effect on multiple channels
Hi Robert, after examining all the options it turned to be the visual system (which is a commercial black box OSG based) doing this somehow. When I attach the osgParticle::PrecipitationEffecte somewhere else in the scenegraph it show to work. So sorry for the false report again. And thanks!

On one of the channels the rain is less dense then on the other two, I managed to get some rain visible by reducing the clip distance on the ClipPlane.

Re: [osg-users] osg rain effect on multiple channels
Hi again Robert, It has to do something with the ClipNode (mimiced code from the osgprecipitation example). On one of the channels the rain is less dense then on the other two, I managed to get some rain visible by reducing the clip distance on the ClipPlane.
