ABC's of Architecture
A Tutorial for Bryce versions 3 and later
There are two lattice objects in the picture above. The two-toned
material was done with ABC mode in the material lab. I used these
arches originally in this image.
This is the greyscale-to-height map used for the arch lattice
object. In the terrain editor, the clipping bracket determines
if the archway is solid or open.
This is the "alpha channel" used in the material lab
in the C channel to determine which areas of the arch get the
pink marble texture and which areas get the stone texture.
Here's how the material lab is set up for the arch object.
The first thumbnail in the C channel is not used, so any
picture could go here without affecting the material. In
order to make sure the C channel lines up with the lattice
object, it's easiest to create it as the alpha channel in
the greyscale-to-height map.
