That would all take a long time to
render, especially if your scene is 30 seconds, 1 minute, or longer. By using the Surface
Baking Camera, you render once, and all the calculations LightWave needs to perform are
saved to an image map you specify. Then, you reload that image, and apply it to your entire
scene. So, one image map contains all of the other image maps, procedurals, reflections,
shadows, and so on.With that, you can turn off advanced ray-tracing features, complex
lighting, and so forth, and LightWave can then crank through the frames for final render
output in no time. The Surface Baking Camera looks at each pixel in your render as a UV
coordinate. (You??™ll learn more about UVs a bit later in the book.) The UV will allow you
to conveniently map a large image around complex shapes. The process can be timeconsuming,
but the camera is optimized to take full advantage of computers with two
or more processors.
The Next Step
The cameras in LightWave are compelling storytelling tools??”whether your story is a simulation
of a car accident, a flying logo, or an animated epic.When you model, you create
shapes and animate them.
