Now that the verticies have been defined, we must prepare the way for the face that will use them.  This is simple and only involves loading a texture that the face will use.  So, click Textures>Load
 

This will open a standard windows box.  Browse to the texture you want to use and click open.  You will return to the binedit work area.  Everything will look the same but, be assured, the texture is now ready for use.
 

Note 1: textures must be in *.raw file format, have an accompanying *.act file, and be either 64x64 or 256x256 pixels in size. Note 2: the texture does not need to be the one you will finally end up using for your model.  It can be anything for the time being, and you can and most certainly will change it later.  The point, for now, is that faces need textures mapped to them, and binedit needs something, any texture, in order to create the face.   If you know the texture you will be using for this particular face, then by all means load it up.  If, on the other hand, you are not certain, then anything will suffice.  A favorite of mine is just a blank arrow that I made.

Okay, now that we're all set, go ahead and click Face>Add.
 

This will bring up the "Add New Face" box where you can enter the face information you need.
 

Part 1 - Face vertices (clockwise!)

Enter the four vertex numbers that define your face (3 if it's a triangel).  Review our example:
 

For us, we will use 0,1,2,3.  Like so:
 

Part 2 - Face texture properties

Click the radio button to select the face properties you want to assign to your model.
 

Unfortunately, this list is short and does not offer all available face types.  If you need one of the other face types, please click here to goto a page that explains how to change face types.

For our example, we will select "color 0 is black" and click okay.  Our face is now defined.

In BinEdit, it will look like this.
