Determine how the element is mapped on a surface.
kFBGeometryMapping_NONE The mapping is undetermined.kFBGeometryMapping_BY_CONTROL_POINT There will be one mapping coordinate for each surface control point/vertex.kFBGeometryMapping_BY_POLYGON_VERTEX There will be one mapping coordinate for each vertex, for each polygon/strip it is part of. This means that a vertex will have as many mapping coordinates as polygons it is part of.kFBGeometryMapping_BY_POLYGON There can be only one mapping coordinate for the whole polygon/strip.kFBGeometryMapping_BY_EDGE There will be one mapping coordinate for each unique edge in the mesh. This is meant to be used with smoothing layer elements.kFBGeometryMapping_ALL_SAME There can be only one mapping coordinate for the whole surface.
