Hey, does anyone know how to make it so if u hit a trigger or after a certain amount of time a brush appears or disappears?

create the brushes. set them as func_brush individualy. give each a distinct name. set each as “asleep” in the flags.

now. create a trigger_once. add the outputs: OnStartTouch, (firstbrushname), awake. check the box that says “fire only once”

do this for all of them.

this may not be exact. but you should get the picture.
