Runs fine in editor/game tab at runtime, goes wonky in actual build

[Solved]

So, this looks to be a long standing bug from Unity. If you have over 4GB of textures in your build, you’ll wind up with all sorts of texture corruption in your build, but it will run fine in the editor. The only way to solve the issue is to use an assetbundle for some of your assets. This has to do with the way that untiy serializes objects.
