Hi! My sculpture turned into this black grid thing and I don’t know what to press to get rid of it! Thanks!
You are in wireframe mode. You can get back to the shading mode you where previously in with SHIFT + Z, or tap Z to get options, or choose in the right top corner of the viewport, among those four round icons, a different one (These are the same options you get when you hit Z key. You have the left most one selected which is wireframe, the full white circle is “solid mode”, the default shading mode, then there is material preview and finally rendered preview).
