Then, you extract one map at a time from Maps/SingleMissions[or A1Single]/ and pack them into an h5m file, preserving the paths.

I think someone might have asked this question before, but I'm too lazy to reread 100 pages in other places, so I'll ask here: How can I make it so that only the 2nd or 3rd upgrade of creatures can be recruited in a castle? And is it really possible to do this with all races, and not just humans? If so, why don't almost any mapmakers do it? It would be great!;;;;Consider it both a question asked and an idea proposed – for example, pitting the 3rd and 2nd upgrades of demons or elves against each other in a multiplayer map – you can come up with a lot of things.

Okay – I reread another forum – I figured it out – thanks, Menty. The answer was somewhere around page 20, I think.

What should I do if I want to upload a map to the website, but when I go to "manage attachments," it says: "invalid file"? Does that mean I won't be able to upload the map at all?

Is the problem still relevant? The issue is likely related to either the file format or the file size.

No, the problem was that I didn't think to upload it through an archive – I've figured it out now, thanks. I hope at least someone will like this creation.

Gentlemen, a rather unpleasant problem has arisen. I finally decided to launch the game today, as I haven't had any time for it before.
The issue is that the "skirts" of creatures and heroes, water animation, and some other effects are heavily lagging in the game (and in the map editor as well). While everything else runs smoothly, with no lag – creature animations, smoke, wind, fire effects, all of that works perfectly. As a result, half of the game is lagging, while the other half isn't, which is not ideal. I tried to figure it out myself, but I couldn't manage it. Has anyone else encountered a similar problem?

I had that issue.
I identified 3 reasons:
1. Computer lag (either CPU or GPU lag).
2. Game lag (with a large number of mods and maximum graphics settings, individual parts may lag or disappear altogether).
3. Corrupted textures.

Heroist, I had the same issue.

2. Game lag (with a large number of mods and maximum graphics settings, individual parts may lag or disappear altogether).

1. I also thought so, but the animations of creatures, as well as other visual effects that should put the maximum load on the video card, work perfectly. And the laptop is relatively new; everything was fine just two weeks ago.
2. I cleaned everything up, changed the settings, removed all the mods, but it's not that, unfortunately.
3. I didn't quite understand; can you elaborate?

1. I also have a new laptop, but it doesn't depend on how new it is... I've seen it on many maps.
2. Then that's not it.
3. Textures are, in simple terms, drawn skins and graphics. The more elaborate the texture, and the more polygons used, the more difficult and resource-intensive it is to animate and render.

1. Let's assume that's true; it's funny, though, that after leaving the laptop unattended for a couple of weeks, it suddenly decided to break down.
3. The thing is, there aren't any particularly elaborate textures right now, and the animations work great. The only thing that bothers me is that the water is displayed very poorly, with dark stripes appearing all the time, and of course, the "skirts" of the creatures slow things down terribly, which makes the game quite uncomfortable to play.

it didn't help me((( I couldn't extract the maps from the campaigns(((

The path to the maps should be saved, except for A1Single - this folder needs to be renamed to SingleMissions.

An absolutely incredible event occurred today: the issue with the game that I described earlier was resolved on its own. When I launched the game today, I was surprised to find that the lag had stopped. It's strange, but that's what happened.

The question might seem silly, but how do you watch replays of battles that people upload? I've downloaded them, but I can't get them to play, no matter what program I use – maybe I'm doing something wrong?

or is it just that the players are being slow?

Battle replays must be moved to the Documents/MyGames/HoMM_V/Profiles/Your_in-game_profile_name/Replays folder. After that, launch the game, go to the settings, find "Replays", and you can watch them there.

Thank you, it was very helpful :)
