Overview

This data is in the same format as Sims_3:0x3D8632D0, with one less field in the header. The data in here is compressed with a very simplistic block compression. The map is split into 16x16 blocks (Or whatever the header calls for) and each is either missing (Indicating no entry allowed), a single value for the whole block, or given individual values for each point. The values are one of three values. 0xff means that the spot is outside the boundry. 0x80 means the camera can go there but sims can not, and 0x00 means that both sims and the camera can go there.
