Tom Sirdevan, real-time rendering guru, provides an overview of the three main types of direct lighting in Unreal 4. By exploring how point lights, directional lights, and spot lights uniquely influence the scene in very different ways, Tom shows how you can build the entire foundation of your scene or level lighting quickly and powerfully while also keeping CPU load down.
- [Voiceover] To begin we're gonna go to exercise files…and double-click on scene one.…This is gonna load Unreal…and it's gonna unload our scene in Unreal.…So when it does load…you can see we have an empty scene.…If we go over to the content browser…and click on levels,…then double-click on begin to load our scene.…And it should show up in the viewport.…And you'll notice by default…that we have this in unlit mode.…
In the early days of video games,…particularly 3D video games,…scenes were unlit.…They didn't have any sort of lighting.…If you look at your texture data…you'll see that it's exactly how it was authored.…If we do introduce lighting,…and we can do that by clicking on unlit…on the top of our viewport…and changing the view mode to lit,…we're going to be in total darkness.…And that's because we have absolutely no lighting right now.…To introduce some lights…we're gonna go over to the modes panel…and click on lights…and we'll drag a point light into our scene.…
That's fairly dim to begin with,…so I'm going to go over to the parameters of the light,…
