Well lately I have seen multiple threads on how to make diffrent colored eyes in ways such as modeling...This is not to put any of thoose threads down im just not the kind of person who likes going into GMax just to change a eye color...
Gimp or Photoshop (I use Gimp)
1)Make a new folder im going to name mine "Diffrent eyes" without the quotes
2)Open KotorTool---Kotor2---ERF's---swpc_tex_tpa.erf---Letter "P"
3)Choose a PC head that you like (Males are easier) double click and save it in the folder we just made.
4)Close the "P" section and open the "N" section
5)Scroll down and save the head "N_SionH.tpc" (Will save as TGA)
The reskin: Im just going to paint and your proboly going to cry at my artist skills but you will get the point.
1)Open up the extracted Sion and PC head.
2)Using the free select select this area. Now for a realistic skin tone switch to your PC head and use the eyedroper to take thier skin tone.
3)Go back to your Sion head and use the select by color tool to select most of the face you can just click in randomish spots you want to end with something like this. This leaves enough of the origional head so we still know what were working with.
