Light layouts are stored in big endian sLL_light.bin (or stgLL_light.bin) files, where LL is the level number. On PC and Xbox, they are located in the /dvdroot folder. For Shadow the Hedgehog, the same format is used in little endian.

File Layout

Each light entry is 0x34 bytes long, and there are 19 entries in each Heroes file, 16 for a Shadow file. Some entries may be blank for some stages, though they can be utilized by objects. The 0x34 bytes of each entry are divided into variables which occupy 4 bytes of space, for a total of 13 variables. They are either longs or floats.

Light Entry

Float values should be between 0 and 1.0f. Less than 0 seems to be treated as 0 while more than 1 may cause a crash.
