• renderFlags (uint8) - unknown

• renderFlags2 (uint8)
  bit 0 - use depth bias
  bit 1 - receive shadows
  bit 3 - unknown, always 1
  bit 5 - enable texture projection
  bit 7 - disable fog

• parentId (uint16) - 0 == no parent, parent must always be before children!

• position (vector3) - in parent coordinates

• scale (vector3) - in parent coordinates

• rotation (quat) - in parent coordinates

• cullingFlags (uint8) - bit 0 enables rendering

• name (pstring) - sectors should begin with “sector”

• params (pstring) - miscelleaneous parameters encoded as text
