The Bent Normal maps within Knald are generated from high to low polygonal meshes via The Baker. While they do contain directional data similar to that of normal maps, they are actually more similar to Ambient Occlusion maps as they include a form of occlusion data via the bent normal (i.e. the occlusion value of the mean ray/weighted average that does not intersect with the high poly mesh after hemisphere sampling) which represents the weighted average of all unoccluded directions.
