How do I use modified textures on clientside?

Hello, I had a question concerning clientside texture modifications in FiveM, for both this situation and how to use this for other textures as well. As of right now I’ve tried a couple methods, but nothing has worked. I am trying to change the texture of one of the masks in game, “berd_diff_001_b_uni.ytd” and I have had this texture working in GTA V before, but I do not know how to work this into the FiveM directory properly. I’ve tried placing the .ytd files in “FiveM Application Data\citizen\platform\textures” as well as “FiveM Application Data\citizen\platform\data\cdimages\mphipster” though neither of these methods have worked. Thank you for any help understanding what I am doing wrong in this process.
