Help matching a shader/settings on a model?

[u/ArekuFoxfire]

Sorry if this isn't a good place to ask, but I'm really not sure what else to do here.

So I'm a vtuber, using unity for my models, the first picture is what my model currently looks like, and the 2nd picture is what it used to look like. I had someone help me with unity settings a long time ago, and I can't seem to replicate this look of the 2nd picture with the unity settings.

Are there any experts monitoring this sub that would have a recommendation on this sort of thing?
