As a gift to the denizens of the server that graciously hosts my crappy maps, I have been working on a festive holiday version of one of the server's more popular maps. On some other holiday themed maps I have encountered, I've noticed that the move_rope cables have festive bulbs hanging off of them. Is this the work of a mod or a custom model? Or is there simply a flag that can be changed in the entity to result in this? Such a change would make a nice touch to the holiday theme.
