To give more depth to the backgrounds I organized the Unreal material in 3 layers:
The first layer is made of the nearest stars: these will appear larger and brighter, because they are virtually closer to the point of view.
The second layer is the nebulae and the last one is made of the furthest stars, which will appear fainter and smaller.
The most dense areas of the nebula hide the far stars in the background through an alpha mask.
