Short description of error
I'm realizing a simple special effect in Motion Tracking, in which a single marker assigned to the tip of a magic wand is linked with an Empty (Track) related to a sphere that emits particles (without gravity).
The intent is that the magic wand generates a luminous trail.
In Blender 2.79 it worked perfectly.
The only problem in Blender 2.8 is that when I launch the rendering, the result is that the clip is displayed and not the 3D objects. It should be exactly the opposite.
Can you check if it's a bug? I attach file.blend. Thank you.
