Re: [osg-users] Problem with OSG Particle System

Hi Dominik, it looks like you have a problem with reference counting: { osg::NodePath fullNodePath = nv-getNodePath(); osg::ref_ptrosg::Nodex = fullNodePath.back(); ... fullNodePath.push_back( x.get() ); } assigns an 'osg::Node*' (from 'getNodePath') to a smart pointer. You later get

Alejandro, I suspect the most likely explanation is this: 1. You are using ShadowTexture, which AFAIK doesn't support self-shadowing. 2. ShadowTexture is ignoring your ReceivesShadow bit, however: 3. When you turn on CastsShadow for a node, it is then implicitly preventing it from receiving a
