I've seen a number of topics about this, so I'm making this tutorial. ^^
Please note that this tutorial assumes that you have a preset made already.
So, let's begin.
First, go to: C:\Feralheart\my_presets.
And choose your preset's folder. Note that it doesn't have to be preset_11 or preset_12, as many people think it must be.
Once in your preset's folder, open it's material file in notepad. You will see all your codes, just scroll down to the very bottom.
Add this to the bottom:
material preset_#_equipMatL
{
technique
{
pass
{
texture_unit
{
texture preset_#equip.jpg
}
}
}
}
material preset_#_equipMatR
{
technique
{
pass
{
texture_unit
{
texture preset_#equip.jpg
}
}
}
}
Note that I have numbersigns in that code. Just change them to your preset's number.
Now, to make the image.
This is something that can be done easily, using the wing shadings as a guideline.
The wing shadings can be found in: C:\FeralHeart\media\textures.
So just make your wing texture, using those as a guide, and name the texture correctly, according to our code.
Then go in-game to Preset Maker, and then click your preset's number, add it's wings, and they should be there!
If you have any problems getting it to work, please feel free to post or PM me and ask. ^^
