How to get Roblox Base part textures?

I am trying to replace the Roblox Terrain textures with the original base part textures as I spite the terrain texture look, and I believe that it would look way better. Please let me know if you have the mappings and stuff for the textures for the material variant. Or if you have a way to pull them directly from Roblox.

This is a little outdated with a few textures missing, but this is all of them pre June 2021.

You can also get them directly from the files I think but you’d have to do some digging…
