Kim, You are correct. Turning off the glare and the underwater depth of field lets osgParticle render on through.
I don't suppose you have any tricks up your sleeve to allow for both alpha textures *and* ocean glare to work? Thanks much - things are looking much better now. -Erik > Date: Fri, 13 Nov 2009 21:02:07 +0000 > From: Kim Bale <[email protected]> > To: OpenSceneGraph Users <[email protected]> > Subject: Re: [osg-users] osgOcean also rendering with osgParticle? > Message-ID: > <[email protected]> > Content-Type: text/plain; charset=ISO-8859-1 > > Hi Erik, > > I suspect this is a problem with the default shader that is applied to > all objects that are children of OceanScene.
