Figure 11-32: Using the IWarp filter to warp the shape of a leaf

To get an alpha texture again, I simply merged
the leaf textures into one layer and then right-
clicked the layer in the Layers editor and chose
Alpha to Selection. Then, I created a new black
layer and filled the selection with white to get my
alpha image. Finally, I exported each of my diffuse,
specular, and alpha passes as .tga images and saved
the GIMP .xcf file, too. The combined leaf textures
can be seen in Figure 11-31. This completed almost
all of the textures for the Jungle Temple. I created
any remaining ones in much the same way as those
described already.

Texturing the Spider Bot
Texturing the Spider Bot was a bit simpler than
texturing was for the other two images because
this project relies largely on procedural materials.
I made a UV texture that covered the body in order
to take some of the hassle out of creating different
materials later and to allow me to add some detail to
the model.

Figure 11-33: I merged the textures for several of my leaves
onto a single image to keep the number of textures in my
scene down.
