I have forwarded to users as requested. In particular it "appears" to be this line 96 P->setPosition(P->getPosition() * worldToPs);
If I remove this line the problem goes away... (work in progress...) ----- Original Message ----- From: "Robert Osfield" <[email protected]> To: "OpenSceneGraph Submissions" <[email protected]> Sent: Thursday, May 21, 2009 8:48 AM Subject: Re: [osg-submissions] Something fishy with ModularEmitter.cpp 8881 Hi James, There must be a difference in the way you are using osgParticle from what the examples are doing that is triggering this problem as the examples didn't break with this change (r8881) from Tim Moore. Tim's submission included other modifications to osgParticle, these are also a topic for current discussion on another thread. So it looks like Tim's changes fix some issues, but introduce new ones. The final solution may well be to refactor the code in osgParticle for tracking coordinate systems. Unfortunately I'm not an expert on osgParticle so am very much in the same boat as yourself and others in terms of having to read the code to understand how it works - this means I can't just pinpoint a problem and come up with a quick solution. Could join the existing osg-users thread on problems in osgParticle or start a new one, so the discussion can go on with a wider coverage, osg-submissions really is just for submissions.
