Static meshes are not rendered as particles when using the Static mesh module in Niagara and setting its source to a static mesh in the scene.
Tested in 4.21.2 (CL - 4753647), 4.22 (CL - 7053647), 4.23 (CL - 7224811), 4.24 (CL - 7225709)
Expected: The particles would reflect the source
Result: The static mesh is not rendered as the Niagara particles
