====== Object Model ======

**Grass Tutorial** By Linker Split

Create a little 3x3m grass block, something like this:

{{ https://pmc.editing.wiki/images/grass_tutorial1.jpg }}

The model must only have some res LODs and Geometry LOD empty, with property names
<code>
damage no
shadow hybrid
</code>


====== Config.cpp ======

Here I'll post an example of what should be to have your own clutters:
<code cpp>

Ok, let's take a look at our Mod config for Mogadishu in descending order:\\
The first part has been dedicated to define my own ground textures, with my own names (city_dust.paa, grassdry.paa and so on) then I defined the class CfgSurfaceCharacters (where you can also change the probability that indicates the amount of objects placed) to add in a second part of the config my own clutters.
So, take a look at the Clutter class part of the config:\\
There you will define your own models to be placed randomly all over the island.
