Before making any changes, please back up your entire Map.


1. Convert densityMap_ground.gdm to PNG with GRLE converter, delete original from map folder. 


2. Copy $&data/maps/mapUS/fieldGround.xml to map folder

3. Edit i3D with text editor

4.1. Change densityMap_ground.gdm to .png

4.2 adjust the numbers for the channels under the "terrainDetail" DetailLayer. Adding 2 here gives 32 angles.


<DetailLayer name="terrainDetail" densityMapId="242" numDensityMapChannels="12" compressionChannels="12" cellSize="8" objectMask="16711935" decalLayer="1" viewDistance="75" blendOutDistance="5" densityMapShaderNames=" blendMap;blendMap2" combinedValuesChannels="0 4 0;4 5 0;9 3 0">



4.3 Under Group "GroundAngle" add the number of channels and the angles. These must be calculated for the number of angles. Here 180/32=5,625


<Group name="GroundAngle" firstChannel="4" numChannels="5" >
<Option value="1" name="-5.625 Degrees"/>
<Option value="2" name="-11.25 Degrees"/>
<Option value="3" name="-16.875 Degrees"/>
<Option value="4" name="-22.5 Degrees"/>
<Option value="5" name="-28.125 Degrees"/>
<Option value="6" name="-33.75 Degrees"/>
<Option value="7" name="-39.375 Degrees"/>
<Option value="8" name="-45 Degrees"/>
<Option value="9" name="-50.625 Degrees"/>
<Option value="10" name="-56.25 Degrees"/>
<Option value="11" name="-61.875 Degrees"/>
<Option value="12" name="-67.5 Degrees"/>
<Option value="13" name="-73.125 Degrees"/>
<Option value="14" name="-78.75 Degrees"/>
<Option value="15" name="-84.375 Degrees"/>
<Option value="16" name="-90.0 Degrees"/>
<Option value="17" name="-95.625 Degrees"/>
<Option value="18" name="-101.25 Degrees"/>
<Option value="19" name="-106.875 Degrees"/>
<Option value="20" name="-112.5 Degrees"/>
<Option value="21" name="-118.125 Degrees"/>
<Option value="22" name="-123.75 Degrees"/>
<Option value="23" name="-129.375 Degrees"/>
<Option value="24" name="-135.0 Degrees"/>
<Option value="25" name="-140.625 Degrees"/>
<Option value="26" name="-146.25 Degrees"/>
<Option value="27" name="-151.875 Degrees"/>
<Option value="28" name="-157.5 Degrees"/>
<Option value="29" name="-163.125 Degrees"/>
<Option value="30" name="-168.75 Degrees"/>
<Option value="31" name="-174.375 Degrees"/>
</Group>

4.4 Correct the start channel under group "SprayType".

<Group name="Spraytype" firstChannel="9" numChannels="3" >


5. Edit fieldGround.xml, contains the information from the i3D in addition to the standard information


<?xml version="1.0" encoding="utf-8" standalone="no" ?>

<fieldGround>
<densityMaps>
<groundTypes useDefaultTerrainDetail="true" firstChannel="0" numChannels="4">

<ranges>
<sowable firstValue="1" lastValue="5" />
<sowing firstValue="6" lastValue="9" />
</ranges>
</groundTypes>

<groundAngle useDefaultTerrainDetail="true" firstChannel="4" numChannels="5" />

<sprayTypes useDefaultTerrainDetail="true" firstChannel="9" numChannels="3">

</sprayTypes>

<sprayLevel filename="maps/data/infoLayer_sprayLevel.png" firstChannel="0" numChannels="2" maxValue="2"/>
<limeLevel filename="maps/data/infoLayer_limeLevel.png" firstChannel="0" numChannels="2" />
<plowLevel filename="maps/data/infoLayer_plowLevel.png" firstChannel="0" numChannels="1" />
<stubbleShredLevel filename="maps/data/infoLayer_stubbleShredLevel.png" firstChannel="0" numChannels="1" />
<rollerLevel filename="maps/data/infoLayer_rollerLevel.png" firstChannel="0" numChannels="1" />
</densityMaps>

</fieldGround>



6. Adjust the path to fieldGround.xml in map.xml          

<fieldGround filename="maps/fieldGround.xml" />

7. Load the map in the Giants Editor, check the log for errors and save again. Then you have a new densityMap_ground.gdm and the PNG can be deleted.
     change densityMap_ground.png to .gdm
