Stealth Prototype in Unreal

This is my second prototype for the stealth idea. When the player shoots the cover it moves out from the wall and this creates a shadow. In the first stealth prototype I created in unreal, the shaded area wasn't dark enough. I tried to make it darker by including two moving covers. Although it did make the shadow darker, this method would not work well in the actual game considering how many cubes the player will be able to move.
