----------------------------------------------------
numVerts        uint8       1
flags           uint32      4    
nearRange       float       4

normal          vector3    12
dotp            float       4
vertices        vector3[numVerts]

• numVerts (uint8)

• flags (uint32) -
  bit 0 unknown
  bit 2 enables rendering

• nearRange (float) - if the camera is farther than “nearRange” from the portal center then scene2.bin objects in the first sector behind it wont be rendered (for both sides)

• farRange (float) - unknown

• normal (vector3) - inverted face normal of the portal

• dotp (float) - dot product of the first vertex and the face normal (non inverted)

• vertices (vector3[])

PORTAL (v41, v42)

v41 (HD2) stores the vertices as vector4, v42 (Chameleon) as vector3
