Inspired 3D: Organic Texture Mapping Tutorial — Part 2 (continued from page 2)

3. Save the body texture. Next edit the texture of the beak. Import the texture map for the beak from Deep Paint. The face projection should be mostly projected onto the top of the beak, leaving the underside blank. Use the clone tool in Photoshop to fill in the lower beak texture. With this model, a thinner, smaller beak is faked by manipulating the textures, so keep the sides of the beak looking like facial feathers (Figure 41).

[Figures 41 & 42] The bottom of the beak is filled in, and the top beak is cleaned up (left). This is a test render of what the preliminary textures look like before clean up.

Details and Clean-up
Small details can push the realism into the realm of photo-realism. These small items can make or break the final image.

1. Take the newly created texture maps and apply them to the color channel of the owl. The rendered image can be seen in Figure 42.

2. You will do final clean up after you have created the rest of the color maps.

3. Next, create the feather textures. Select one of the feathers of the model and export it out to Deep Paint. Create the striated pattern of the feather on the feather geometry. This is accomplished using a combination of photographic texture reference and hand painting. Once again, you have two different colors for the top and the bottom (Figure 43).

4. The individual feathers will require bump, specular and transparency maps in addition to the color map created in the previous step. For the bump map, individual ridges on a feather should not be created, which would cause crawling or moiré in the finished rendered image. Simply draw a faint line for the stem of the feather (Figure 44).

5. For the specular map, it is only necessary to break up any specular hits and keep the values low. The Photoshop cloud render was used to create the specular map shown in Figure 45.

6. Because this model does not have the many layers of feathers that an owl has, a transparency map should be applied to the tips of the feathers. This will help give the illusion of depth and give a more realistic look to the owl in flight (Figure 46).
