It's a combination of two things there. So we have screen space reflections, SSR as you've already called it. That's okay, but it's got a nasty tendency that the falloff, which is called Fresnel, on the surface, it's not a linear gradient. So it cuts off really harshly on very shiny surfaces, and of course water is very shiny. So what I've done there was — we've got the ability to, you put a light in the center of that globe, we're able to tell the light to have what we call a bulb radius. So the radius of that globe, I think, is like 1.5 meters, so I'm able to put in a diameter on that of three meters, and then you get a perfect reflection. So you set the intensity very, very, very low, and then you get what you saw: it's an absolute perfect reflection of what is essentially a gigantic light bulb. The key with that stuff is that we want to get that then dynamically changing to the hologram tech when that comes in.
