Fog draws at the layer’s real alpha (1.0 = fully opaque for host and players). **Lock for players** is a quick toggle that sets layer-default Draw/Move/Delete to Deny; fog layers are always locked for players (move/edit/erase rejected on the host). Players also **cannot hide or fade** a fog layer (eye / alpha); only the host can toggle fog visibility, and the host rejects client DisplayData that would strip FoW. FoW visibility is still global (not per-person).
