Hello,
My project had no issues on old computer.
I am now on a new computer (entire project just on a different drive letter).
Opening my project, the material instances texture inputs aren’t loading all of my textures (seemingly at random). When checking the Asset → Migrate, I can see all the appropriate textures are referenced to the material instance in some way.
Replacing the texture input manually, and re-checking the Asset → Migrate path for that texture, the path and name are Identical.
I have no idea what to do, as this has bricked my entire unreal project completely.
