UE4 mixed reality plugin issues

I have set up the unreal mixed reality plugin with my project and performed the full calibration. The issue I am experiencing is that it is only rendering part of what is happening in my scene. In my game, you are able to fire a variety of projectiles, particle effects, and spline meshes from the controllers. The capture texture renders all the projectiles fine, but seems to ignore all the particles as well as the spline meshes. Even though I can see them in my headset or normally through the mirrored display, they do not show up when composited through the epic MR plugin.

Hello,
