Hi Bill, Do you have a ModularEmitter and ParticleSystemUpdater? If so, where are they in the scene graph?
Are you expecting the particles, after being emitted, to move with the transform or stay in the world coordinate system. ---- Tom Jolley ________________________________ From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Poirier, Guillaume Sent: Monday, October 05, 2009 12:09 PM To: OpenSceneGraph Users Subject: Re: [osg-users] MatrixTransform and particle system Yes sorry I should have mentioned that...

However if I add another geode like this before the previous code: osg::ref_ptr<osg::Geode> pDummy = new osg::Geode; pDummy->addDrawable(particleSystem.get()); addChild(pDummy.get()); Then I have one set of transformed particles and one set of untransformed ones. Probably I am missing something simple here ? Anyone has a suggestion ? cheers ! bill
