Notes

  • Almost all maps have a light of type 38 (if data 1 is "type"). The only exceptions are B2_08, which is inside Drakenhof Castle, B4_10 (Black Grail Knights), B5_01 (Dread King) and SPARE9 (tutorial).
  • However, the dialogue indicates that these values are "E and L falloffs". This implies that there are NO directional lights, only point lights. So what are these falloffs? Light attenuation and falloff function (~= range)?

Bitfield

It is very likely that data1 is a bitfield.

  • All values are lower than 63 (63 corresponds to binary 0b111111)
  • there are only a limited number of values
  • values tend to cluster to "toggle areas"
