[osg-users] Outlining a node (Beginner)

[Julien Valentin]

Hi Lex
I'm afraid the community knowledge around this feature began to fade with time...
Personnaly I avoid using old parts of osg (osgFX and osgParticle for ex) because a lot of techniques used in its features have evolved in a way that new hardware are not fitted anymore to them.

Perhaps asking the original contributor of OutLine directly could be your best bet
