I am sorry, but I am not good at writing in a fancy format in Byond forum.

This will be very helpful especially for lighting system because if I make a lighting effect has `ignores_mob_sightings = IGNORE_SIGHT`, the lighting will be rendered regardless you can see the light source loc or not.
Lummox JR resolved issue (Not Feasible)
The sight flags you mentioned aren't really doable, I'm afraid. I don't think it'd be possible to do IGNORE_SIGHT, and IGNORE_BLIND is a definite no.

IGNORE_INVISIBILITY won't work in vis_flags because invisibility is handed at a much less granular level. If the parent object is invisible, the routines that handle filling icons for its appearance and visual contents never get called at all.
