I have this bizarre and really annoying issue where the Plane mesh primitive is missing from the modes panel. The issue isn’t specific to the project, but the engine. I found the folder that these assets are stored in and the plane is missing, tried copy-pasting a Shape_Plane.uasset file in there and no luck on relaunch. I’ve been using my own plane .fbx for use in-game but UE4 seems to reference this primitive for material previews etc, which is really annoying because it’s not there! Pls help… I am a relative novice in UE4, and I’m loathe to re-install atm because I’ve got deadlines coming up and don’t want to have to re-download asset packs that I’m using from Epic Games. Ugh.
You can fix it by pressing the verify button. It will take some time but ue4 will check all its files and only download the missing/broken parts.
