cheap, quick way of
approximating
the
look
of a reflective surface.
f.
Under Reflection Map, choose
(load
image
) and select
Images\_Reflec-
tion_Image_TA.iff
.
Render away!
Figure 4-36: Somewhat less than excellent, huh?
We've got to go into the Basic settings and tone
some things down. (Subtlety.)
g. Items that r
eflect
light cleanly do not
generally also
scatter
it as well. So,
knock the Diffuse down to
30%
.
h. I've found that even the most reflective
of real-world things don't reflect as well
as LightWave's 100% Reflection set-
ting calculates. Change the Reflection
setting to
55%
.
Render again.
Figure 4-35
e. Under the Environment tab, select
Ray Tracing + Spherical Map
from
the Reflection Options pop-up menu.
The options under Reflection Options are:
•
Backdrop Only
“fakes” reflections by
making
only
the
backdrop
appear to
“reflect” from the surface.
•
Ray Tracing + Backdrop
adds “true”
reflections to this (when you have Ray
Trace Reflection active under the Render
Options).
•
Spherical Map
“fakes” reflections
using
only
the image used as the
reflection
map
.
•
Ray Tracing + Spherical Map
adds
“true” reflections to whatever image you
are using as a reflection map. (If you have
no reflection map image specified, this is
just ray tracing over black.)
Figure 4-37: It looks a lot more like the chrome
sphere is sitting in among the other objects now.
Even though we can't really see the things the
sphere is reflecting, we've been trained to think of
chrome looking something like this.
