[osg-users] osgFX::Outline lose material color while GL_LIGHTING set OFF

[Ulrich Hertlein]

Hi Franco,

From the png I understand that you have a Group with Geodes A and B.
The effect will *always* be applied to the entire node that it's attached to, so if you
want to have the outline only on A or B then you must attach the effect to A or B, not the
parent Group.

Hope this helps.

Cheers,
/Ulrich
