I was assigning textures to an asset that I created in blender. I had different parts of the asset divided into different materials. When I was putting the textures onto the asset. Two of the materials came up as world building material. Not really sure how that happened. Just wondering how I fix my project?
Navigate to Documents\Unreal Projects\YourProjectName\Content
I’d try removing your blender assets and then the textures. Copy them somewhere else if you need. If that doesn’t work, I’d give the post a bit for other people to help. And if no one does you can salvage most of your work from the content file.
I had the same issue before and I had to remove the bad asset then duplicate the project then it started working.
