I created basic force field shader using Unreal 5.4.1. Main key function is Fresnel', 'DepthFade', and 'Band'. I set up the color parameters for emissive, and the rest of the textures, Fresnel and dept fade for Opacity.
This function puts texture animation in band shape arong the mesh surface with width and sharpness input values. And I additionally used the panner node to adjust the animation time.
If we want to add a more complex function that moves by pattern, I may use a different type of procedural node.
Lastly, I felt basic texture looks pretty simple and too clean. So I added one noise texture on main texture because I thought there would be a disruption when the energy shield working. We can add various effects later by adding vector values here.
