Figure 11.99
Set the attributes for the displacement image.
Figure 11.100
The carvings are displacing outward.
6. Render a frame, and compare it to Figure 11.100. It's not looking very good. The box
isn't exploding anymore, and only the carvings are displacing, which is good. How-
ever, the carvings are sticking out, instead of in.
7. Set the Alpha Gain attribute to -0.05 to push the carvings in a little instead of out. Ren-
der, and compare to Figure 11.101. The carvings are set into the wood as they should
be, but the render looks bad. The displacements are very jagged and ill-defined.
Figure 11.101
The carvings are
inset into the wood,
but they don't look
good yet.
