I opened a project I made about two years ago for the first time in a while. It is version 5.3, and it is a project from the days before Fab existed.

The material function is gone, and I’m wondering how to restore it. Does anyone know what that is?

If that is difficult, I would like to change it to the parent of the Megascan material sold at the fab.

But there are so many that I don’t know which one is suitable. ㅠㅠ
