if you have mapped your model already (meaning it's ready to receive the texture), all you have to do is assign the texture to its .mdl file. You can do this by using various programs, such as vertexmodify or mdl pather (all found in the tools section in this forum). Also, you can add the texture to the .mdl file manually. It's not that hard, you just need to be careful not to write anything wrong or it will mess up your .mdl file. open you .mdl using notepad and search for something such as:
Textures 1 {
Bitmap {
Image "",
ReplaceableId 1,
}
}
That is the place where you insert your texture. Say you have a folder called "models", and inside it you have your model. Then create another folder inside "models" named "Textures" and put you .blp texture there. Then you add that path to the .mdl file, e.g:
Bitmap {
Image "Textures\yourtexture.blp",
}
You must then set the number or textures according to how many you used, and you must keep that line that says "replaceable id". So, if you have 4 textures, it would look like:
Textures 5 {
Bitmap {
Image "Textures\texture1.blp",
}
Bitmap {
Image "Textures\texture2.blp",
}
Bitmap {
Image "Textures\texture3.blp",
}
Bitmap {
Image "Textures\texture4.blp",
}
Bitmap {
Image "",
ReplaceableId 1,
}
}
