I was having so trouble with decals, I decided to follow this.
It helped my issue, but when I reloaded the project all my textures were low res and very blurry.
I’ve since reverted the changes I made and reloaded but my textures are still low res and blurry.
I started up a new project to see if it was just my project issue, but upon starting it, the starter content also had shading issues.
I reinstalled and the issue is still there.
