Hi everyone, I have a problem with light. Later, my scene should be consist of a multitude of planetary system each lit by a light, and for this reason that I would have several light0. I have also seen the project osgmanylights but this method doesn't suit me. For now, I have done a

Hello, there is a bug when we use an osg file to create a scene including osgParticle system and a geode using a shader. If the geode and shader code are read before the particle system, it's ok. But if the particle system is read before the geode and the shader, the shader is not read. In fact,

Thanks for the quick reply, Robert. It's really the flattening that I require, and not necessarily the type change. For example, I see that osgconv doesn't change the type of the top level Transform node, but it does flatten it so that its transform is the identity. In my app, however, this top
