MAP Format specifics

This article will be quite extensive, since the format of the map is large enough. The format is in many ways similar to BND, it also has "sections" with "names" in its set, with its own peculiarities. The file with the map is also accompanied by a file with a texture and a texture mesh (for 3D geometry). The following sections are found in this file:
MAP0 - a section with a description of the map itself (geometry, logic, collision)
D000 (0,1,2 ....) - Dynamic objects on the map, such as doors \ elevators \ other objects

Despite the fact that the file has few sections, however, the section with information about the map itself has many "blocks" that are not marked with anything and information about them is only in the header of the section itself. This article will describe all the blocks that have been found empirically, as well as their structure and formulas by which they are calculated.
