1. Open the file "map01.i3d" with the "Editor" or my recommendation is to open it with "Notepad++".

2. Click on edit -->search and enter the word "SubLayer".

3. You should now have the sublayers in front of you.
   
   Example:
   <FoliageSubLayer name="wheat"

4. Note: If you change the value "numBlocksPerUnit" (changes the density of plants) it can influence the performance.

   Now enter the values below, it's best if you enter them with copy + paste.
   Attention! You have to enter the exact values! There can be no extra space signs or similar!




FoliageSubLayer name="barley changes barley values:		numBlocksPerUnit="1.9" width="1.5" height=";0.25;0.5;0.9;1;1;1;0.9;0.13"


FoliageSubLayer name="wheat changes wheat values:		numBlocksPerUnit="1.9" width="1.5" height=";0.25;0.5;0.9;1;1;1;0.9;0.13"


FoliageSubLayer name="grass changes grass values:		numBlocksPerUnit="2" width="1.4" height=";0.25;0.6;1.0"


FoliageSubLayer name="rape changes rape values:			numBlocksPerUnit="1.5" width="1.5" height=";0.25;0.6;1.4;1.6;1.6;1.6;1.2;0.36"


FoliageSubLayer name="maize" changes maize values:		numBlocksPerUnit="0.6" width="5" height=";0.875;1.55;2.75;3.35;3.35;3.35;2.75;0.325"


FoliageSubLayer name="potato" changes potato values:		width=";0.45;0.5;0.9;0.8;0.8;;;;0.3" height=";0.4;0.7;1.0;1.0;0.7;;;;0.1"

Changing the windrow height:
The value for windrow is always the same, thus it is always one of the following values:

FoliageSubLayer name="wheat_windrow 				
FoliageSubLayer name="barley_windrow				height="0.7;0.75;0.78;0.82;0.86;0.9;0.94;0.98;1.02;1.06;1.1;1.14;1.18;1.22;1.26"
FoliageSubLayer name="grass_windrow
FoliageSubLayer name="dryGrass_windrow
