Steps to Reproduce
- Create a new Niagara System (pick any emitter template, make sure it uses a Mesh Renderer).
- Select the Mesh Renderer and add a mesh to the Meshes array.
- Override binding “MeshIndex” with a UserParameter (int32) so you can manually select index.
- Set index to 1, mesh doesn’t render.
- Set index to 0, works fine with any mesh.
Expected Result
Mesh index > 0 = visible
Observed Result
Mesh index > 0 = invisible in editor, fine in game
