In photoshop CS5, we could already paint on a 3D object. So, we could add color, we could add some nice structures, but it was not really fun. It was rather slow so that, at least, I tended to avoid that. In Photoshop CS6, this has been improved and let me show you that. First, I create a new document by hitting Cmd and N. And choose a File Size, of let's say, 800x800 pixels. So, I choose a rather small file so that the performance will be very nice here.
So, I hit OK and now I want to create, let's say, a soda pin, and that's quite easy. I'm already here in the 3D workspace, and here I choose Mesh from Preset, and then the Soda Bin. All I have to do now is to hit the Create button, and there it is. And now I can choose a Brush, choose a Color. So, that's painted red, and not the tone. And if I start painting, you see, that's quite responsive. But the color is not what I wanted.
It should be a little more reddish and not like this orange. So, I paint over it again. Well, you could paint color already in Photoshop CS5, but now you not only have color, but you can paint different things on the texture. And you find this under Paint On Target Texture. You see now I painted the Diffuse Color, but you can also paint in Bump, Specular Color, Opacity, Shininess, Self-Illumination, Reflectivity and Roughness. And let me show you in this video how you can paint in a Bump effect.
And Bump is something that is not really there, but it's just making the impression that there are some little holes and rough structure on the surface. And for this, I choose a black color. So, I hit the letter D. I make the brush a little bit smaller. Do a right-click and choose some interesting brush here. Let's say I'll take this one. It's the Grass brush and I can paint here.
And then, we should see some bumps after we saved a Bump Texture here. And we choose the same File size, 800x800 pixels, okay? And now, I can paint in the Bump effect. So, if I have a look at the Layers panel now, I have a Bump layer here, Label Material Bump, and that's necessary in order to paint in some Bump effects. What you see is created automatically. You just have to fill in the File Size and Pixels.
Hit OK, and everything is done. And now you see, I can make some nice structures here. And let's try to add some Shininess, 3D, Paint and Target Texture, Shininess. And for that, I choose another brush. Let's say, a round, soft brush. And now, again, you get this warning or this hint, that one or more materials in this 3D layer are missing a Shininess texture.
New Shininess textures will be created for those materials to enable editing. Well, I want that so I click on OK, choose 800x800 and OK. And now, I can paint in shininess. Now, that's quite nice. So now, I've painted over another material. So, it wants to create another layer for Shininess for the other material. So, I hit OK. And again, I fill in 800x800.
And now, I can paint over these areas, and paint in some Shininess. And in this way, you can combine all these parameters to create the surface you want for your 3D object. Let's say, you want to add some reflectivity. Then you have to choose it in the Paint On Target Texture. And then, you just have to click once on the object. Let Photoshop create the Texture layer, tell Photoshop how big it should be, hit OK.
And now, you can paint right away and add this texture. But you have to be aware, if you paint over another material, you will have to add another Reflectivity texture for each and every material. So, this can be quite tedious to always hit OK, enter the values, and hit OK. And then, paint again but at least it's fun once you know how these things work. And then, you can paint in some scratches like this.
Paint in some reflections and you see, I only painted on the surface and that's always then the case. If you don't want to rotate this object or animate it,and if you just see the front side, why do not just paint on the front side? Well, if this is the new feature of Paint On Target Texture, and this is quite powerful. But if you have a lot of materials here in the scene, it's quite tedious to create all those Bump maps and Shiny maps and Reflectivity maps.
You see we have two here for the shininess, one for the kept material, one for the label material, and so on. But once all those materials are created, you can just paint away and have some fun with these Paint On Target texture features.
