Hey I was having this exact problem and I got it working. I’ll just go through the steps I took to trouble shoot. So first I was trying to import a 4.7 file to a 4.6… so make sure the versions are the same. It still wasn’t working so I double checked my path (I have multiple copies of the same project, probably NOT super intelligent but y’know.) So turns out I was pathing to the wrong project. Then I did what Andrew said and deleted my asset registry to force it to look at the assets again. From that point it worked, I just had to re-build the textures because for whatever reason the materials were still build and the textures were there, it just didn’t recognize the connection. Hopefully you guys derped like I did and it’s an easy fix for you too.
