Unreal Project and editor Whited out

I opened my project today (on the day that I finally needed it), and the entire editor is greyed out (still can use it), and my entire project is bright white. I can’t build, and when I play the game in the selected viewport, it is still whited out, but I can kind of make out the geometry in the level. When I play the game as a standalone, it looks just fine, like it did previously.

All of my other projects behave just fine.

Anybody have any Idea what’s going on?

For contrast: here is what the editor normally looks like on my screen! This is with a separate project open.alt text

Anyone have any ideas? I’m still stuck and have been borrowing another computer. It works on that computer, but not on mine.

I think I figured it out finally. Saw this post: https://answers.unrealengine.com/questions/143055/weird-glitch-my-entire-project-including-ue4-edito.html.

The Media assets in the project were causing these problems. I’m really hoping I can get them back into the project, because they’re important for what I’m doing. If you have any advice on that, let me know. Thanks.
