@Sprouttower Unfortunately, due to a recent VRChat update, I doubt that anyone will be able to rip assets until a new ripping method is found. VRChat has implemented a system that encrypts the cache storing avatar data, which people have been using to rip for the past few years.
I don't know if you have the base model, but there are two topics on the RipperStore you can keep tabs on while searching for it LF: ENA VRChat Avatar + MMD By Callista (don’t be fooled by the MEGA link—it’s the wrong file, a GMod ENA model), and LF: ENA by HaruMaki.
If the texture is a custom one made by the user who uploaded that avatar, then I doubt you'll be able to get it, with ripping being unavailable to most people right now.
If you need help with anything or have questions, feel free to ask. If you'd like to check out the current RipperStore discussion about the encryption update, you can visit this topic: → VRChat added VRCA & VRCW encryption
