I personally tried VamX... and well... Let's just say that while it worked for me, after a bit with it active, the program would just... straight up crash. Idk if this is an issue that has since been fixed, or if it is still a pending issue yet to be fixed.
To import custom models
1. Download the .var and put it into addonsfolder (or download using the hub inside the game)
2. Open the
scene that contains the look. (for some reason people share a scene instead of the appearance preset)
3. Save the appearance preset (click on the girl (go to root),
appearance presets tab, name it, save it, take the screenshot)
4. Load any other scene, and load the appearance preset
5. (optional) Use plugins to make this process easier (UIAssist, Scene Ninja)
To give them a good fucking
1. Download the scene you want (Suggestion: Kittymocap is the most straightforward)
2. Download the dependencies
3. Put everything into addonsfolder (you can also use the hub inside the game, much easier to get the dependencies)
