Need help making tri for a ported custom head

[Riskbreaker]

Hi guys. I ported a character from another game and everything was going smoothly until I got to making the damn Tris. I need to make brand new tris with shape keys for this custom head, I exported the head as OBJ in OS then imported it in Blender and used the vanilla shape key names and changed one of the expressions, then exported it as tri but when I load it in CK it crashes CK and my game both. I can't find a proper tutorial from scratch on custom head tris anywhere either. This is driving me insane. Can anybody help me with it ?

 Hi, I'm planning to do it myself. I did 80% of the work but the tris are being so difficult.
