Oh sorry then,
I'm just asking: what is the effect of calling
lightSource->getOrCreateStateSet()->setAttribute(light,
osg::StateAttribute::ON);
I guess that's just *stupid* to add a Light structure as a StateSet for the
LightSource that already has this Light structure, but I'm just trying to
understand the strange lighting that results.
Thank you.
