I’ll make you a little tutorial because i’ve got a few of these asks and there isn’t an up to date tut out there that I know of.
What you will need: Sims4Studio, the mesh file you wish to edit. (Sims4Studio requires a free registration but it is well worth imo.)
Place the mesh file somewhere you can easily find and open it using the My Projects button in S4S like so:
You should then see this screen. ^
You want to click the Warehouse tab, next to the Studio tab which is currently open.
In the Warehouse tab you want to select ‘Type’ so that the parts are ordered by type, this makes it easier to delete the ones you don’t want.
Select all of the CAS Parts and RLE 2 Images you can see and press the Delete button on your keyboard to leave only the mesh:
This will make it so when you place the mesh in your mods folder the MM version reads the mesh and shows up and you don’t get the original textures clogging up your game. 🙂 I tried to be thorough but if there is anything you don’t understand feel free to drop me an ask and I will elaborate! Happy CC Management! ❤
