We do plan on making promo videos for most of our content.

You have to change the whistle kuid in order for the whistle to change. Open file manager then search the engine you want to change the whistle for. right click and open config file. Then find the line that says engine horn/whistle. Now in a separate tab find the whistles you installed. you'll have to search for it (for example Reading 6 Chime) you'll have to type it in exactly how its written, so find the downlead file or download it again to find out how the creator spelled it. Example - If the whistle's name is written RDG 6 Chime, searching Reading 6 chime will not find the right whistle. Now once you've found the whistle you want to use, get the kuid # listed off to the right. Now go back o the engine config file and delete the original whistle kuid # and replace it with the 1 you want. Then save and exit. Once that's done you'll have to submit the edits on the engine. right click on engine and click submit edits. And you have changed a whistle. Worth note, I would definitely duplicate the engine before editing. Just in case you mess up or wan the original whistle back. If you mess up the engine will say faulty and you wont be able to use/spawn it until you fix whatever is faulty. Best advice would be KZfaq a video on it, there are plenty.
