AutoVTF: A tool that lets you forget about needing to convert to VTF, as if Source uses normal image formats. And with hammer++'s hotloading, texture iteration is no longer a hassle :D
(You can edit the textures of models like this too)
I explained everything in the github page:
github.com/NvC-DmN-CH/AutoVTF
It's inspired by how Godot imports assets btw.
