Nanite Tools break some Engine meshes

Hi !

Actually, the Nanite Tools enable Nanite for all contents, including Engine Content. I’ve now some BasicShapes from the Engine like Sphere, Plane, Cylinder, … with Nanite enabled and they doesn’t work anymore in other projects where they are using unsupported features.

I can’t disable nanite manually for them because they seems to be in read-only mode.

I suggest that Nanite Tools should work only for Project Content.

Thx !
