Hi,
Ok, I got it, it's only an issue on 4.7, and I guess you are on 5x
Can you test this package and tell me if things works now, you should have now both the class and its derived class.
You'll need the latest version of PlayMaker as well, since I also updated the modified actions to use the latest official versions from 1.8

<assembly fullname="UnityEngine">
<type fullname="UnityEngine.ParticleEmitter" preserve="all" />
<type fullname="UnityEngine.EllipsoidParticleEmitter" preserve="all" />
</assembly>

The package is available on the
Ecosystem.
Thanks,
Jean
