Mesh lights and sample rates

- [Instructor] In addition to using the lights to illuminate our scenes, we can turn any kind of geometry into a light source through the use of emissive materials. So in this scene currently, the geometry is illuminated just by the octane sky and the environment that we have here. Now what we'd like to do is turn these cylinders, which are in a mograph cloner into lights. And so, we set up this cloner with the random effector to randomize the position and the color. So we're going to use that when we create our emissive material. Now to create emissive material, we need to use the diffuse type. So, we'll create a diffuse material, and double-click it. We will just apply this to our cloner and we'll double-click this to open the material editor. Let's just rename this to light. And we'll work in the emission channel. There's two types, you could use blackbody emission or texture emission. I'm going to use blackbody and immediately you see the live view update. Now, this has become a…
