===== What does it do? =====

//atFilterAM// is a calculation plugin that provides methods to merge different land types in the attributes map, or to convert them into alpha layers. Unlike the conventional [[bundydocs>l3dt:userguide:ops:alpha#generating_alpha_maps|alpha map generation]] interface in L3DT, these filters are pre-defined, so you don't need to manually combine layers.
