How to pick and highlight a modelnode with the mouse？
I now use osg::osgUtil::Intersection to select the model, and it works.
But something went wrong when I tried to highlight the model.
I tried to use osg::osgFX::Outline, but it didn't work well.
I refer to the method here.
I can changes the color of the model，but I don't know how to get the original color of the model.
What I want to achieve is to let the model change color temporarily when I select it.
This is probably an OSG problem, but I wonder if OSGEarh has a relevant method?
I'm sorry if it bothers you.
