Connecting the
reverse node to the
fractal node
10. MMB+drag the reverse node on top of the fractal1 node, and select Other from the
context menu. This opens the Connection Editor, which you first saw in Chapter 3.
On the left is loaded the reverse1 node, and on the right is the fractal1 node. In the
left pane, click the plus sign next to the Output attribute, and select output.X. In the
right pane, select the alphaGain attribute, as shown in Figure 7.63.
11. Open the Render Settings window by choosing Window
➔
Rendering Editors
➔
Render Settings. Click the Maya Software tab, and set Quality to Production Quality
in the pull-down menu. (See Figure 7.64.) Render a frame: you finally have a bump on
the tire and a smooth rim. See Figure 7.65.
12. It's not a very convincing bump yet, so select the fractal node and set Ratio to 0.85.
Click the Placement tab for the fractal (it should be called something like
place2d-
Te x t u re 6
), and set the Repeat UV values to 18 and 48, as shown in Figure 7.66.
Doing so makes the fractal pattern finely speckled on the tire.
13. Render a frame: the fractal's scale on the bumpy tire looks too strong. Double-click
the bump2d node in the Hypershade, and, in the Attribute Editor, set Bump Depth
to 0.04. Render, and check your frame against Figure 7.67. The bump looks much
better, if not a little strong from this angle; you can finesse it to taste from here.
