The two sliders control the five bits that determine the placement of the Special Resources and the Minor Tribes (Huts). The Special Resources location is calculated using the low order 4 bits controlled by the slider on the right. This formula limits the placement of the Special Resources to sixteen different patterns. The left slider controls the high order bit of the five bits that control the Huts placement. The Huts have thirty-two different patterns. The Special Resources and Huts are locked together by the value of these five bits. There is no way of controlling the placement of an individual Special Resource or Hut map square.
The placement of the Special Resources and Minor Tribes, or as commonly known Huts is controlled by the following formula.
[((X \ 4) * 13) + ((Y \ 4) * 11) + TerrainMasterWord + 8] and 31 = (X And 3) * 4 + (Y And 3)
For any given map square X Y the game applies this formula with equality a Special Resources exists.
The sliders alter the value of the low order 5 bits of TerrainMasterWord.
The
control buttons in the Huts box (Show Active, Show All, None) control the visibility of the huts only within the TerraForm program.
Set value updates the value of the TerrainMasterWord as determined by the sliders
Special Resources on little map shows where the Special Resources would be for a given value.
Reset to value to original in file Just that.

If one needs to have Special Resources outside of the pattern see:
CIVMAP21 revisited
This is outside the scope of the game but see
CIVMAP21 revisited if you really need to do this.
I'm not sure what you are indicating. Where is this
black rectangle?
