If you have in your mod folder the sirenmod folder and the sirenmod.zip if it still doesn't work did you tried to remove all your mod and keep only the mine :/ ?
I have both of them in there, and I clean my mod folder, but still no horn or siren, everything else though. The new car sounds, and the environment sounds.
The dirt sound and other things like this work ? If no i don't know if yes i think you forgot to put the lua file in the game folder and bind the key
okay i got it working. and a note to others that downloaded it but the horn doesn't work, you have to set a bind for the horn and siren. for the siren you have to put m, and it'll say it will have a conflict with the other bind, siren lights. so enable it anyway, then got to siren lights, and delete the bind there.
I think the radiator fan sound is WAY too loud. I think it should be quieter, or removed indefinitely.
You can disable it if you don't like it, personally i disabled it You can enable and disable each features in: "Documents\BeamNG.drive\mods\sirenmod\config\settings.json" Just look for the feature you want to disable and replace true by false
The MOD you made was great! Come on! But sometimes the smoke is too big for the computer to run smoothly. Would you please improve it?
