trong hai chương cuối cùng, bạn đã học cách không gian làm việc trong các chức năng 3D Photoshop để cho phép bạn tạo, thao tác, và thay đổi giao diện của các đối tượng 3D bằng cách thay đổi màu sắc kết cấu, của họ, và ánh sáng | CHAPTER Using Photoshop Tools to Change the Appearance of a 3D Layer In the last two chapters you learned how the 3D workspace in Photoshop functions to allow you to create manipulate and change the look of 3D objects by changing their color texture and lighting. In this chapter I show you how to integrate 3D objects into the Photoshop workspace using the tools you are probably more familiar with to paint over your 3D objects and create adjustments styles and filters. The last section of this chapter walks you through some very complex exercises that demonstrate some of the tools and techniques that can be used to create a successful composite with 3D objects and images. At this point you should be familiar with all the techniques used to create these composites but completing these exercises gives you practice using these tools and shows you how they can work together. IN THIS CHAPTER Using 3D Paint mode Adding image adjustments to 3D objects Creating great composites 3D Paint Mode You can grab a paintbrush in Photoshop and start slapping paint on your 3D objects. The paint conforms to the 3D object because even though you are looking at your 3D object you are changing the texture file which is wrapped around your 3D object. This gives you the distinct advantage of being able to change areas of the texture as it is mapped to your object instead of trying to guess where to paint in a flat rectangular texture file. You can paint color onto your object of course but you also can paint texture shine opacity and reflection onto your object. This makes the 3D Paint tool a versatile way to change the materials of your 3D object. 757 Part VII Working with 3D Images Before I show you how to use the 3D Paint tools I show you options for selecting areas of your object to paint on and hiding areas of your object that you want to protect. These options in Photoshop are definitely a little rough around the edges literally as well as figuratively still they can be useful. Hiding
