I'm not sure I can help you with this old technique. If you are creating faces for PES 2013 I can't definitely, it's been over a decade. Might check the comments below for solution, because I remember some people had similar issues with the script. The technique is quite simple in newer versions of Blender (2.79 and after) by going to Object Data Properties tab (the triangle icon, third one from bottom up) -> Shape Keys -> dropdown icon Join shapes and you pull the slider to max. Before that in Object mode first select the modified Facegen face then the original one. Once done delete in Shape Keys menu the original face shape key, then the modified Facegen one. Otherwise the shape reverts to its original state. The last paragraph is meaningless if you are using Blender 2.49 specifically for PES 2013, because of plugin incompatibility. Sorry I can't be of much help and good luck.

@@IsakIsakov wow, just the fact that you've answered made my day mate. Unfortunately I'm actually trying to make pes 2013 faces, I tried deleting the edges and faces of the f001 except for the borders and left the playet obj ones in, I don't know if the fef file needs the texture to be in the f001 "slot" but I'm so noob at blender that I don't know how to clone or copy from one file to another besides your tutorial (which unfortunately doesn't work for me 😅🤦) I'll keep trying though, thank you very much for replying, you gave me hopes to keep trying. Hope you are doing well 👍👍
