Painting Blendmap
Now, let's make things less green!
Go to the Basic Toolbar and select Terrain Texture Painting

This system works almost identically to the Terrain Height editing, except that you're painting textures. The main interesting feature to note is the Channel property. this defined what textures to use on the map. They're named by the texture type, not the texture itself.
• In the Brush Properties Window, set the following:
o Flow: 0.25 (I like to keep the opacity low and layer the texture rather than just dropping it down)
o Channel: mud01
• Start painting onto your terrain in the same way as with height painting.
You can hold SHIFT to go into smooth mode and smooth out any edges Pressing ALT and clicking will sample the Blend Map at the cursor position allowing you to quickly swap between.
Once this is done, you should have some nice looking mud textures on your tile.

Painting Vegetation
Now for the fun part. Let's paint some Trees!
When you paint Vegetation is this way, you're not just painting texture, you're defining which areas of the map the game treats like forest, as well as an area where trees will be dynamically generated.
Forest only works if the sum opacity of the Forest texture is greater than 60%
In the image below, you can see the blendmap painted at three different Opacities. Note how the density of the trees lowers depending on the opacity.

You may have noticed in the previous step that you can also do this from the Blend Map Mode. Since we use forest so much we added a separate button to make it more accessible.
Let's get to it!
• Go to the Basic Toolbar and select Terrain Forest Painting. This will select the Blend Map Painting mode, do not be afraid.

• Make sure your opacity is greater than 60%
• Start Painting
Remember that forest doesn't always exist in one big lump, there are paths, clearings and differing densities within.
• You may notice that the tree don't appear straight away. This is because they're being generated on the fly whenever you make a chance. while this is happening you should see the following in the bottom right hand side of your screen:

All being well, you should end up with some forest on your map:
