Hi,
How can the light node only affect the node which I specified?
The structure of my scene is:
root
/ \
child1_group child2_group
/
light
I hope the light can only affect the child1_group,but the child2_group also be
influence by the light node.How can I deal with that?
Enable the light in child1_group, and disable it in child2_group.
osg::StateSet::setMode( GL_LIGHT0 + index, osg::StateAttribute::ON (or OFF) );
