This plugin is honestly a lifesaver, especially since it does sounds for sprinting as well! I had given up on my project because I was struggling with adding footsteps about a year ago before this came out, so this is much appreciated!
I have only two complaints though, one is that there's no wood floor tag, minor complaint really. The other that it returns an error when you walk on a terrain that doesn't have any of the sound tags allocated, that is a pretty big problem, but I understand this has been discontinued so it's fine.
(For anyone downloading this, I'd recommend editing the files to add a line that uses a silent OGG sound file for footsteps on terrains with the terrain tag 0. You can also add your own terrain tags this way)
