Hi Robert,
I tryed with OSG-2.8.0 (had to patch it a little bit, see my other thread),
and the issue concerning the billboarding is fixed indeed.
However, my problem remains about lighting.
Any idea ? Do you think it'd be used that I re-try my attempt to feed
normals per vertex (I see in 2.8.0 implementation that they are still not
established) ? - Wouldn't explain that at least the ambient doesn't work
though... -
Any idea is welcome !
Christophe.

HI Christophe,
Could you please try the OSG-2.8.0-rc1 as there was a fix for this issue.
Robert.

Hi All,
While updating my end user application from OSG 2.2.0 to 2.6.1, I noticed
some bugs appearing onto osgParticle/ concerning the use of particle
systems
whose alignment is BILLBOARD : emitted particles seems to behave anymore
as
billboard sprites. Relinking with OSG successive versions, it seems that
the bug appears as early as with OSG 2.4.x...
I just wanted to ask if some people have already stated this issue and
maybe
isolated the reason of this bug (maybe located into
osgParticle::ParticleSystem::single_pass_render() implementation, that
has
moved since 2.2.0) ?
I also wanted to know one thing : has someone already tryed to use
ParticleSystem with not emissive particles ??
I'm under the impression that lighting in the scene (ambient as well as
diffuse) hasn't got proper effect onto rendered particles' sprites : they
remain black even when sharply lighted in the scene. I've tryed (onto
ancien
2.2 implementation) to set/patch per vertex normal values (playing with
osgParticle::Particle::render() and
osgParticle::ParticleSystem::single_pass_render() implementation), but
that didn't seem to properly solve the problem.... I wanted to ask if
someone had a different approach in mind about a possible problem
patching ?
Thanks !
Christophe
