The pack comes with example scenes, FX, Color Grading profiles, and prefabs.
The team states that each element has been carefully crafted with in-game use optimization in mind. “This asset was fully created in Unity3D engine. All elements are combined with the latest standard shader, Shuriken particle system, Animator for animations & each element is packed into a prefab, so you can just drag-drop the element with spaceship controller and start flying in a beautiful environment”.
