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
