Just like Tokoa has mentioned, you can use those four images for an example

To make an actual material though you will need to copy and paste an already existing .material file and re-name it.
Let's open up the Rocks folder for example, Feralheart>> Media>> Objects>> Rocks. See that rock.material file? Copy and paste it then rename it to something like
snowobjects for example.
Once you've done that you will need to open it with a program called
Notepad.
Right-click the
snowobjects.material file and select
Open With. Then you should be able to choose the program Notepad. If you only have the
Open option you may get a box like this:

Just choose the
Select from a list of installed programs option and you should be able to choose Notepad from there

Once opened in Notepad, this is what you'll see.

{

}
Of course these are the materials for
all the rock textures, so you can delete five of them so you're left with
one.
Before we go ahead to the next bit you should choose the image you want and rename it to something that's easy to remember and find. Copy the image of the snow texture and paste it in the
Rocks folder with your .material file and rename it.
material
rockMat{
technique
{
pass
{
ambient 0.1 0.1 0.1
cull_hardware none
cull_software none
texture_unit
{
texture
rockTex.jpg }
}
}
}
Now we can start editing

Don't worry, it's really simple to understand ^^
We are making a new material name, how about SnowMat for example. This will be the name we will use to type in Object Maker to get the actual texture to show.Here we will just type in the image name and format. Replace the rockTex.jpg with the image you've pasted and renamed. If you're using the textures from your terrains folder than leave the .jpg, if you downloaded one off the internet, make sure you know if it's a .jpg or .png.We should end up with a slightly changed .mat file.
material SnowMat
{
technique
{
pass
{
ambient 0.1 0.1 0.1
cull_hardware none
cull_software none
texture_unit
{
texture snowimageTex.jpg
}
}
}
}
Lastly go
File>>Save, not Save as. Now, if we open up Feralheart and load a mesh in Object Maker we should be able to use the new texture. Select the object and go to the Mesh tab, in the Material box type in the new material name. For example I would type
SnowMat then I'd hit Enter on my keyboard.
Hopefully that should help you make a material, if you need any further assistance please let me know
