Static vs. dynamic lighting
- [Instructor] Lighting is arguably the strongest single feature of Unreal Engine, so let's make the most of it. When building a realtime visualization in Unreal, our goal is a responsive, realistic experience. To do that, we'll need to balance our lighting solution between static and dynamic lighting. Precalculated, or static lighting, bakes shadows into special UV coordinates called light maps, and it's best for lighting the bulk of the unmoving scene. Since it's calculated in advance, more time can be spent on those ray traces to achieve very subtle, high quality lighting effects. The drawback is any moveable objects in the scene will either have their shadows baked onto the floor, or none at all. You can see here that there's still evidence of this, even though I've moved it. That's where moveable, or dynamic, lights come in. Since these lights are calculated at runtime, they can cast live shadows as the light, or other objects, move around the scene. Let's take a look at one of…
