Hi All,

Billboarding issues appearing with OSG 2.4.x onto particle systems is greatly 
fixed into OSG 2.8.0, however the issue concerning absence of influence of the 
lighting onto non emissive particle effects (that is present at least since osg 
2.2.0) remains.

Has someone else also stated this bug with maybe a working bypass correction 
for it ?
(I tryed myself while back with osg 2.2.0 to set normals onto particles vertex 
at rendering, but that was an unsuccesful attempt to fix the lighting problem : 
particles remained invariably black).

I'd be glad to know of any ideas about the reason or a way out of this problem.

Christophe
