Removing artifacts from meshes
Is there any way to remove meshes that are wrongly modelled? We have scanned a model, and it seems that someone stood in front the entrance for a while, and the camera considered his head as an object. Now we have a floating artifact in the middle of the entrance. Can it be removed?
I'm not talking about modifying the mesh, as far as I know we can't do it, but this is a floating object, not connected to any other thing, so I think that it may be removed easily (technically speaking)?
