A hilt i downloaded overwrites the arbiter hilt but i simply want to just add it without overwriting any of the default hilts. I looked in pk3 and theres only a model folder and whatever I do to rename it, it either shows up in game without the textures or shaders (grey) or completely invisible. too add on to what i said about the models folder the .glm file is saber_1 How would I change this if i need too
