Question Why can't I delete these surfaces?

[123yerongtian]

I'm cleaning up a scene. But I found a few surfaces that I can't delete. Nor in the selection menu of atoms. They can't be selected either. How should I delete such please?

Are you sure they're not just hidden? If you select Show hidden in the select atoms panel, they might appear.

If not, they might be added through code directly in Unity. In that case I think you need to hard reset vam to get rid of them.
Otherwise I think something is bugged with a scene you loaded or an asset.

There are no hidden resources in the scene. I have saved the green wall separately. If time allows, could you please help me to see what the problem is?
