I challenged myself to make a map based around handmade textures. Sorry.

5 levels of death, Minecraftified! Each floor has 2-3 perk machines and shield parts. This is gonna be my last map for a while, but I plan to make more fun challenge maps and stuff in the future.

You probably figured it out a long time ago but for anyone else that gets this, i'm pretty sure it will come from incorrectly installing something related to ui. Usually a perk machine. (Maybe always idk fully, it relates to the in game perk icon shaders in the bottom left of the screen, you know what I mean.) I believe it can happen when placing a ui folder included in a download in the wrong place or if it isn't able to read it because you don't have the necessary stuff. You probably don't have l3akmod, which you need to read .lua files for black ops 3. I got this error after incorrectly installing PHD Flopper.

How do you fix it? Like fix the install?

So I've started working on a small map just to mess around with stuff. I installed some assets from Devraw, and they all work perfectly except the actual models. I'm assuming I'm missing something, but I followed the instructions exactly and the models don't show up in the prefab editor at all.
 
I also added some scripts the same way and they work fine, so I'm sure it isn't something I did wrong. I must be missing something.
