Photoshop CS6 is also much better at allowing you to control the relative position of your 3D objects. So you can select multiple meshes, you can align and distribute them, and you can move them as a group, none of which you could do in CS5. And this becomes immensely important when you're crafting 3D scenes that contain multiple meshes. For example, in the case of this scene, we have three reflective spheres which are listed here in the Layers panel: front sphere, left sphere, and right sphere. And they are all housed inside of this gigantic Spherical Panorama.
And we are inside that sphere and the sky and grass are mapped onto the interior of that giant sphere. And I was able to combine all these objects together by assembling them independently in the Layers panel and then selecting the layers, going up here to the 3D menu, and choosing Merge 3D layers. Now, that part I have done in advance. But the problem I have is that these spheres are out of alignment with each other. I want the scene to have a certain symmetry to it. Now, in CS5 I would have had to have moved each one of these spheres independently, but in CS6, let's say that I want to take this left sphere, and I will go ahead and Shift+Click on right sphere as well, I want to align those two spheres to each other.
Then I will switch over to my Move tool, and notice these alignment options up here in the Options Bar, those icons have been there for a long time now. However, only in CS6 are they applicable to a 3D scene. I'm going to go ahead and click on Align bottom edges in order to align these two spheres to each other. There's a little bit of bugginess going on where the shadow preview is concerned in this specific build; hopefully it will be reconciled in your version of the program, but we will clean that up when we render the scene. Now I'm going to Shift+Click on this forward sphere in order to add it to the selection.
And then I will go up to this icon, which allows me to Distribute the centers horizontally, so I can distribute these objects as well as align them. All right, now, with all three of the spheres selected, I'm going to drag up on this blue arrow to move all of these spheres upward to right about there, actually looks pretty good to me. And now, I'll switch back to my Rectangular Marquee tool and I will press Ctrl+Shift+Alt+R or Command+Shift+Option+R on the Mac in order to render out that scene. And you can see that it cleans up very nicely. Now, it is going to be noisy. In the case of image like this, one that has complicated lighting and soft shadows and so forth, the initial passes of the ray trace are going to look very noisy, but each additional pass will reduce the noise.
Now, as usual, we're going to speed up the process a little, and you can see when the render completes that it cleans up quite nicely. Now, we do have a problem here. I'm going to switch over to the Layers panel. Notice that these two spheres, the left sphere and the right sphere, are casting shadows onto, not only the grass, but also onto the sky, which doesn't look particularly credible. So I have created this layer Mask in advance, all I need to do is Shift+Click on it in order to turn it on and mask away those shadows. And that's how you select, align, distribute, and move multiple meshes here in Photoshop CS6.
