When the same particles are displayed in the inspector in the osg file and the osgt file,
In the osgt file, particles appear to disappear at half-lifetime.
OpenSceneGraph sample (

I think cessnafire.osg and cessnafire.osgt have the same result, but with cessnafire.osgt, the smoke disappears on the way.
Is this a specification?
