well mate in Epilogue think NCSOFT make another protection for this, is same like weapons,armors, when try make new one you can't because client give you critical error
I know what you mean, you say that when you equip the top of the armor layer is equipped also, that you can do with UnrealEditor but am not sure if it worked with two different things, I did with the wings of the Kamael.
good if there is a way of making them smaller, modifying the 3D model, and about what the echanting look at weapongrp that has a value of an effect "LineageEffect.c_u007" example, only must go two values back and change the value -1 for 1 and when you start see effect.
well how say before is a new protection of NCSOFT, don't know what need change for fix that but is not hard, I do it before but can't remember how to fix x.x
well you can do it man, just extract all textures and make new l2font-e.utx and import all textures you extracted and you don't get critical error more eh ok hope help you good luck
