What steps will reproduce the problem?
1. create a particle effect that has a transparency on its particles...

What is the expected output? What do you see instead?

I'm having a problem with my particle generator when i use it in the same
scene as osgOcean (dtOcean). All the transparent alpha pixels seem to glow
instead of being invisible. Also the particles transparency value has no
effect anymore...so instead of slowly vanishing...the particles just pop
out of existence.

attached is a screen shot of what i get....the picture shows a screen with
and with out osgOcean (dtOcean)....notice how the particles look...

i tried disabling the glare shader....but that had abs no effect....

i also noticed that it matters from which side you look at the
particles.....sometimes the transparency gets semi fixed....so i'm thinking
its a lighting thing...but don't know...

What version of the product are you using? On what operating system?

osgOcean 1.0.1
and dtOcean (part of Delta3D)

Win XP VS2008
