BigMediumSmall - INFECTED - Modular Character Bundle

Models are great.
But unfortunately, all Material Functions are missing from the project, which completely breaks every material in the scene.
I tried reaching out to BigMediumSmall through various channels (including LinkedIn), but received no response.
The same issue exists in the version sold on Gumroad (yes, I was naive enough to buy it there too).
I’m sorry, but I have to leave a 2-star rating until this is fixed.
