/atom/movable/emissive_blocker

Internal atom that copies an appearance on to the blocker plane

Copies an appearance vis render_target and render_source on to the emissive blocking plane. This means that the atom in question will block any emissive sprites. This should only be used internally. If you are directly creating more of these, you're almost guaranteed to be doing something wrong.
