Mesh optimizing

- [Instructor] Unreal has some impressive features for simplifying meshes, right out of the editor. Let's open up one of these office chairs here, and take a look. On the left of the viewport, you can see a few statistics about the asset. The one we're interested in is this Triangle count. As you can see, we're nearly at 38,000. Now, that might not be a lot for this one object, but when you copy it a few dozen times in the scene, it can really add up. Let's see if we can fix this. Head over the the Details panel, and scroll down to LOD zero. Here, you'll find a Reduction Settings option, let's go ahead and expand that down. Now, I know it seems like it's too good to be true, but click on the Percent Triangles, and add something like 50. And you'll see, when we apply changes, the Triangle count immediately drops. And yet, I can't tell much of a difference with the chair. Let's take a look at the Wireframe, and see if we notice a difference when we drop it to 20%. Big change, now let's see it in the light. Still can't tell the difference, and yet we've saved ourselves 30,000 Triangles, per chair. It's never a bad idea to look at your project through an optimization lens, and Unreal Engine has great tools for this. So use them.
