Occlusion Pass

3m 39s

In this course, Ramy Hanna will teach you a basic understanding of Photoshop, all the way to using advanced tools such as actions.

First, you will learn the basics of Photoshop starting with setting up various windows and gaining a basic understanding of the tools. Then, you will learn how to add additional elements and blend them into a rendering or photo seamlessly. Finally, you will learn how to manipulate existing photos, and how to remove or add elements with a photo.

When you are done with this course, you'll know how to significantly enhance the color and quality of any photograph, including architectural renderings. There are 2 parts to this course:

Part 1- Exterior Renderings in 3ds Max: You will learn how to take an exterior building model through all the important steps required to create a convincing photo-real rendering.

Part 2- Photoshop for Architectural Renderings: You will learn how to significantly enhance the color and quality of any photograph, including architectural renderings.

Some of the other elements that we can add are the occlusion pass. So let's take a look at that. So this one, again, this adds shadows to your rendering, and soft areas. And So we don't want it everywhere, but we do want it in certain areas. And so let's go ahead and add that, and I'm going to simply just drag it on top and hit enter. And let's go back to our layers. And there it is. This is, right now, it's on top of my rendering, and what I want are the shadows. And so again, we talked about blending modes.

There's one where the white is transparent, and the black is opaque. That's a multiply. So let's go ahead and set this to a multiply and see what happens. And you can see now we have some very dark shadows. If I turn that on and off, you can see the effect we're getting. Now it's too dark in certain areas, and so I want to control where those shadows are, so I'm going to create a mask, and I'm going to set this to black.

So CTRL I, making everything on this layer visible, and I am going to paint with white, and I'm going to add. Basically I'm going to paint the shadows in areas that I want. So as I come into, for example, this area down here where I have these plants, I can create more contrast by adding shadows in the certain areas. Some of it is just understanding light.

So we know that the bright areas are on the left, and the dark areas are on the right. So I'm going to paint the shadows on the right side. So here we go. And it's just giving me a little more contrast. And it's a nice way to paint shadows in using your occlusion pass. If you want things to feel more grounded in your scene, you can simply paint them in this way. For the most part this one's feeling pretty good.

We're adding more shadows. And the shadow areas, basically, we're painting them in. And typically I do not use an occlusion pass set to a hundred. I use a very low, small amount, maybe 30%. That's feeling pretty good, but you can see now by toggling that on and off, you can see the contrast we're getting in some of those plants. That's going pretty good.

In addition to a multiply, I will also use a soft light blending mode. And let's go ahead and delete this mask, and set this to soft light. Basically what this is is brightening of the whites, and so I'm not gonna have it at 100%. Typically if I do a soft white on the occlusion pass, I will not go past 10%. But this is an overall brightening of the image, especially in the areas that are dark.

So if I have areas that are dark, it's going to bring out those details in some of the dark spots. And we're at 30% here. It's feeling pretty good. But you can see it's not goin to be too dark in some of those areas. So a combination of a multiply and the soft light gives me a little more reading information in my rendering. You'll see that areas that were super dark are now a little bit brighter.

And it's giving me a little more contrast. And for the most part, that's how I use my occlusion pass.
