Particle display is different between osg file and osgt file

[Takahashi]

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 (https://github.com/openscenegraph/OpenSceneGraph-Data)
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?
