The deep texture explorer is accessed by option clicking in the first swatch
in texture A, B, C or D, providing a procedural texture is selected. The
presets menu allows for the saving and deleting of textures created by the
user, or the presets provided with the program. This image has been annotated
to explain the various functions of this area.
It is also an imagemap, and by accessing those areas, it is possible to
see the contents. (samples only, which may or may not relate to the material
shown in this particular graphic.)
