Culling Groups in Unity is a powerful but often overlooked API that lets us tap directly into the engine’s visibility checks and distance bands. In this video we build a custom system that goes beyond Unity’s default frustum culling, with simple on/off toggling, then adding smooth fade in/out effects. Along the way we break down how bounding spheres work, how to register and deregister objects safely, and how to keep everything in sync between Unity’s native system and our managed code. By the end, you’ll see how Culling Group can be used not just for performance, but also for polished gameplay effects.
