Missing texture files on weapon geometry

[KeatonSW]

Hi! This is my first time posting as I'm new to modding, I am just trying to teach myself file paths and basic reusing of weapon models and changing their properties to get started making custom units. Right now, I am trying to use the "seeker" weapon msh for the Republic engineer (giving the clone engineer the rebel engineer shotgun model), and I've gotten the model to appear in-game, but it's all white and is lacking it's texture. Anyone know what file I may have forgotten to copy over or what the issue could be? Thanks!
