Hi Schauk,
I’m not sure exactly what’s going on, since I cannot reproduce this with default settings and simple meshes for my scene.
I’ve setup a simple 2D scene capture camera and I have both a movable and static Sphere Shape mesh that seems to work.
Can you verify if simple objects like that are working on your end as well? If so, it could be mesh specific, in which case select the mesh and in its Details Panel check to see if “Render in Main Pass” is unselected, or if Actor Hidden in Game is selected.
If that still doesn’t work, can you try in a new project and see if this is still happening?
Let me know.
Tim
