Join Donovan Keith for an in-depth discussion in this video Using blurry transparency to create frosted glass, part of Production Rendering Techniques in Cinema 4D.
Glass is a transparent material, and in part its quality is judged by its clarity.…However, not all glass is perfectly clear, and in fact, some of it is quite cloudy.…Blurry transparency allows us to simulate imperfect transparent objects.…Here is a rendering of a bathroom scale that has perfectly clear glass.…In fact, it's not really clear what this object is just looking at it.…However, when I choose the Blurry transparency, immediately this becomes recognizable as something…that we've probably seen in our bathrooms or at least on somebody's Pinterest Board for a bathroom.…
And this is something that is often called frosted glass.…It's created by taking a perfectly clean piece of glass and then just roughing up the surface…at a very fine level and to simulate this is really pretty simple. But before we do this,…I want to get into how refraction works. So, let's take a quick look at a graphic here.…Reflection--as we saw in our previous video--occurs when light hits our object and then it bounces off.…
