The current “Flicker” light function available for Condo lights is the most awkward of the available options. It’s more of an “uneven pulse” than a flicker since its transitions are smooth, and the value ranges from off to full power.
On multiple maps in Zombie Massacre there is a unique light flickering effect that looks much better. It’s most easily seen on a lamp to the north of spawn in Compound (and possibly the campfire as well).
It would also be nice to have access to the Water Caustics effect that exists on the Default Condo’s pool lights before editing (it can’t be reactivated after changing) as a new effect.
