What I'm trying to do is change the skybox based on tf_logic_on_holiday. For example, if the holiday is April Fools, set the Skybox to the Pyroland skybox). I can do this easily in a SourceMod plugin, but I'd rather have it set up in the map. I figured I could use a point_servercommand entity to fire off the sv_skyname convar with the new skybox, but I was hoping there was some way of changing the skybox within the Map Properties via tf_logic_on_holiday's outputs. EDIT: Is it also possible to change the textures on specific brushes with the holiday logic? I assume if I use func_detail, I can *maybe* use it for things like wherever there's grass (like displacements in a forest area) and change the texture to snow for a Christmas holiday. I've already got some April Fools logic set up by the way. Here's what I've set up if anyone is interested in fun ideas they can implement on their map. Click to view the full-sized image. Pretty much inverts the spawn rooms so that RED spawns in BLU's spawn, and vice versa. Also takes care of switching the resupply lockers and the doors to leave spawn so players don't get stuck. Takes a lot of work setting everything up to work like this. I'm already pretty much naming every entity/trigger using a dedicated naming structure which you pretty much need to do if you want to have any sort of control over all the entities in the map on the fly for things like a SourceMod plugin or holiday logic.
