- [Instructor] Let's continue from where we left, so the refract basically determines how much of the light passes through the surface, so if I make it 100% transparent by changing the color to white and hitting OK, the next important value will be the glossiness, and by default, it's set to one. This means that the refraction would be very strong and it will be very clear. If I change that to a very low value, let's say to 0.25, and this gloss has already this material, what's going to happen is that one, the rendering time will be a bit increased, and why? Because not all of the rays will be passing through that. Instead, the glass will become a bit foggy, and if I render that out, it's going to take a lot of time but all I want to prove is that it will not be very purely refractive or I would say transparent and there will be a lot of fog on the surface of this glass. So higher the value by changing back to one, which is the maximum value, will allow a lot of light and let this…
