Render away!
the softness I want in the reflection without
setting Antialiasing to an amount that takes
much longer to render than I care to wait.
(Which is also the reason I'm not quite fond
of the Reflection Blurring setting under the
Environment tab — it takes tons of AA to
get it to look good.)
Luckily, there's an image filter that
LightWave ships with that softens reflec-
tions. Image filters are applied after
everything else is done and then access the
data LightWave generates as it renders,
using that as a map to modify the final,
rendered image.
Figure 4-40: The “micro” bump map that we
added causes the reflection to be dispersed as it
gets farther away from the surface it is reflecting —
just like in real life.
Note
Remember, in order for smaller and smaller
textural details (like the “micro” bump we
just added) to be properly interpreted by
LightWave's renderer, you need to increase
the antialiasing level. The smaller the detail,
the greater the level of antialiasing needed
in order for it to be properly rendered.

off any reflections in the render.

The render in Figure 4-40 is pretty good,
but I want to see it look better. What's both-
ering me about it is that we can see the
little pieces of reflection that the bump map
is dispersing. I've tried making the bump
map even smaller, but it doesn't give me
