I'm currently using the Blow Horn Imperial marker to make one my guards blow a horn every 10 minutes, but they're not Imperial guards so them blowing a imperial horn doesn't make much sense. Anyone know how I can make a new blow horn marker with a custom sound?

Bump, no one know how to do this?

Go to the IdleMarkers, copy the one you're using and modify it.

When I right click the marker in the Object window and use edit. I don't have any options really to edit the sound, only to choose a new idle marker. I've looked around the Creation Kit and can't find the list or a place to edit the markers in the list.

The sound may be part of the animation that goes with the idle. The subject came up in a discussion on Fore's FNIS mod, either here or on the nexus. If so, I'm not sure how you'd change it.

Use BlowHornStormCloak marker ?

Could you link the thread the question has already been asked in?

Not sure, but try this one:
