You were asking about stopping the combat music from playing AFTER combat was over, not starting it. That's exactly what the autosheathing code handles by detecting end of combat, pretty successfully if I read their readme correctly. The game seems to detect combat start well enough.
Send me a link, I'll take a look at it. The problem is if the DM scripts aren't disabled during combat, then they will eventually interrupt the battle music if you've been in battle for an extended period of time. It would be useful to be able to detect combat end though, as it is now, as soon as you exit combat, the Mw Explore music starts up, then you have to wait around for a few minutes or so before the Dungeon Music starts up again.
BTW, sorry to hijack this thread, but I just downloaded both your Detailed Tapestry replacers from TES Nexus, and both are flagged as broken files by 7zip (CRC and data errors). I tried a couple of servers but got the same results from both. Is it possible for you to rezip your source and upload again? The problem files are tx_de_tapestry_01.dds and tx_de_tapestry_02.dds. I don't suppose it's a coincidence that these are the last and first respectively in their zips... You didn't split a bigger complete RAR somehow by any chance? Or hit an upload limit at TES? The remainder look absolutely stunning, it would be a shame to lose these...
I have tried downloading them in the past, and the files are fine, try downloading again, or download them from PES. Also, please keep discussion for my mods in http://www.gamesas.com/index.php?app=core&module=search&do=user_activity&search_app=&mid=474532&sid=ba16817c7e32e2fc61faded74d4170a5 next time, unless there isn't one (I guess a lot of my [RELz] and [WIPz] threads died after the forum change).
