Description

If using a Stationary directional lighting with object that have disabled dynamic shadow casting will lose their statically cast shadows when the dynamic lighting is in range.

See attached image and video for clear example.

Steps to Reproduce

1. Open UE4
2. Place a mesh in the scene
3. Select the mesh and disable dynamic shadows
4. Select the directional light source and set the cascades distance (I used 1000 for closer proximity)
5. Build Lighting
6. Move closer and then further away from mesh to see result

Results:
When moving within range of the cascaded shadow maps distance the statically lit shadows will fade out if the option to disable dynamic shadows has been checked.

Expected:
If the dynamic shadows has been disabled for any particular mesh this mesh should not receive any dynamic shadows and should not cull the view of the static baked shadows that are outside the distance range of the cascaded shadow maps.
