Wow, I haven't visited here in ages....but that's mostly because I haven't done any mapping whatsoever until now, when I decided to start working on a new map for my trade server. So I'm currently messing around in Hammer (for TF2) with func_rotating and logic_timer. I'm trying to recreate those neat rotating posters from Half Life: Source and the somewhat-recently-released Black Mesa game which appear within the very first part of the game in the lab. I have a faint idea of how to make this work but when tested in game, the func_rotating brush I set up doesn't rotate. Here's what I've got set up so far: The rectangular brush should rotate 90 degrees every 7 seconds...I think. The logic_timer The func_rotating What am I doing wrong? Is there a tutorial out there on recreating those rotating posters? Specifically, I'd like to recreate the Black Mesa ones as those have a smoother rolling effect to them. I found and decompiled the map using BSPSource, but when loaded up into Hammer I can't do anything because Hammer freezes for about 2 minutes any time I click anything because the map is so large.
