Do you have a couple of questions about mentoring?

You can use mods from other sources on the forum, but you must always credit the original author and, ideally, provide a link to the mod.

.h5u and .h5m are archive formats.

You can convert to .ogg manually by renaming the file or using online converters like convertio.co. So, for a mod that replaces music, you need to: 1) Create the same folder structure as in the game directory. 2) Take your music files, rename them to match the original file names, and place them in the corresponding folders. If it's not clear: in the music folder, there's an a2 folder, and in it, there's MainMenu.ogg. Let's say I want to replace it with my Rammstein Sonne.mp3. I create a folder on my desktop named music, in it, I create a folder named a2, and in the a2 folder, I put Sonne.mp3, which I rename to MainMenu.ogg. Done. To install this "mod," you need to put the music folder into the game folder and, when the system asks if you want to replace files with the same names, answer yes. In general, we're replacing the game's files with our own.

The Biara model is located somewhere in Characters/Heroes/DialogScenes/, and you can select it for Jezebel using the method described in my guide "How to create your own hero," but instead of creating a new shared file, you edit what Jezebel already has.

P.S. I have no idea what you did or how, so I can't say what's wrong. To combine all the mods into one, you need to open each one with an archiver and put them into a common archive, which you then rename to h5u.

Understood. Luckily, the link where I got the mods has references to some of the authors =).

Since these are just archives, does the game somehow interact with the archives and determine where to put them when the executable starts, or something like that? You don't manually put the model folders, etc., into all the game folders. They're just put together in one mod, which you place in UserMODs.

Thanks! I'll keep the converters in mind.
1) Should the folder structure look like this? For example: Heroes of Might and Magic V - Tribes of the East\music\a2\New Music, but with the name of the music I want to replace in the game?
Or, according to your example, is it enough for the mod to use only the music directory as the main one?
By the way, is there any information on the forum about the music in the folders? Which directory contains which sounds for the Warlords of the East?
And you mentioned "In general, we're replacing the game's files with our own." - Is it possible to make the game play the mod's music without replacing the original files, using the .h5u file in UserMODs? Or are music mods required to replace the original music without fail? (I might not be explaining my thoughts clearly here on the forum, but I'm trying to make it clearer. If something is unclear, you can ask).

I don't have a "Characters/Heroes/DialogScenes/" section at all.

Can you provide a link to the guide?

P.S. I created a UserMODs folder. I put a bunch of small mods that change the hero models in .h5u format into it. Then I archived UserMODs and renamed the extension to .h5u (I created a kind of nested mod 😀). But in the end, the game refuses to start this way.
