<p>The Extents TAB:</p>
|
|||
|
|
<p>Extents:</b> The extents of a map are the points on a map that define its
|
|||
|
|
lowermost t and leftmost corner and its uppermost and rightmost corner. They are
|
|||
|
|
given in terms of X, Y coordinates.</p>

|
<blockquote>
|

|
|
<font FACE="Symbol" SIZE="2">
|
|||
|
|
<p><EFBFBD> </font>Under Extents, you should chose number values that are even
|
|||
|
|
multiples of your number of Divisions so that the grid rectangles are all
|
|||
|
|
the same size (this produces better texturing results). It also makes extra
|
|||
|
|
work for the compiler. Furthermore, use the Extents to position the terrain
|
|||
|
|
entity on the map (XY only). You will want to make sure that the terrain
|
|||
|
|
locates exactly where you want it each time you revise it. Repositioning a
|
|||
|
|
terrain file can be time consuming.</p>

<font FACE="Symbol" SIZE="2">
|

|

<p><EFBFBD> </font>Set your X and Y divisions to equal the number of rows and

columns of triangles you want. You may want to strongly consider playing
|

|

with the numbers so that your triangle sides end up be large powers of two
|
|||
|
|
(64, 128, 256 units etc.).</p>

the size of the triangles is consistent and constant.</p>

<p>The Bitmap TAB:</p>

</b><font FACE="Symbol" SIZE="2">
|

<p><EFBFBD> </font>Filename should point to the .bmp file you are using as a height

<font FACE="Symbol" SIZE="2">

<p><EFBFBD> </font>GenSurf assigns an integer value to each of 256 shades of gray.
|
|||
|
|
The value is based on the position of the color in the palette. In a grayscale
|
|||
|
|
palette, the values typically range from 0 (black) to 255 (white). Map Color 0
|
|||
|
|
corresponds (usually) to the lowest point on the height map and Map Color 255
|
|||
|
|
to the highest. If you set Map Color 0 to 0 and Map Color 255 to 2048, each
|
|||
|
|
increase in color value adds 8 units to the height of the vertex. When you
|
|||
|
|
increase the difference between to the two values, the height changes are
|
|||
|
|
steeper. Decrease the difference and the height changes are more global. You
|
|||
|
|
can control the <20>Z<EFBFBD> location at which the terrain draws by adding any
|
|||
|
|
extra height above (or below) zero to the height values for both numbers.</p>

<p>The Fix Points TAB:</p>
|
|||
|
|
</b>
|
|||
|
|
<p>The general recommendation for this TAB is to leave it alone. You should
|
|||
|
|
either modify the height map or directly manipulate vertexes inside the
|
|||
|
|
Q3Radiant editor.</p>

<p>Once you<6F>ve tweaked all your settings, do a Save as. If you make changes to
|

|
|
the settings, consider saving again as a new file. It<49>s nice to have a back up
|

|

if you screw things up.</p>
