 Okay, so we're going to create the glass. We're obviously back into text from here So we need the hyper shade open again, and we're going to create a new material So clear the work area, and we're going to create a blend because this is going to be reflective and shiny I'm going to call it glass M and then I am going to give it a color. I'm going to give it a tinge of Kind of blue so kind of a cartoony feel to Window, but you're not going to be able to see because I'm going to take the transparency Almost down to the right so you can see this is kind of the effect that it gives so it's quite quite see-through And then we just need to apply that material in the same way that we would any other material so I'm going to Put this into face mode, so I'm right clicking here choosing face and choosing the face that I want to apply it to Then I'm right clicking on my glass material and I'm going to assign that material to selection like so Now that creates a really cool glass material so for the time being we can close the hyper shade again and If you want to you can create a quick test render I'll be seen with the glass in place to see what sort of effect that's having you won't be able to see much because There's nothing outside of the window yet to see But you should be able to see that it's black and that there are reflections on it So there you go. That's my glass At the moment it just looks kind of like a mirror But once we put something outside the window that is lit it will look very cool
