Legal aspects of modding.

Technically, it is possible to use assets from Heroes 7. Moreover, it is much easier than using assets from Heroes 6, because Heroes 7 was made on Unreal Engine, and they didn't put much effort into it. This means that you can easily extract models, textures, and skeletons with animations from the game. It's a pity that you can't directly import the skeletons with animations into Heroes 5, and you'll still have to adapt them to the native skeletons of Heroes 5, plus, again, you'll have to reduce the polygon count. But from a legal point of view, I'm not entirely sure. It seems that as long as you don't sell these assets, it's okay, but it also seems that it might not be. However, in order for someone to sue you, it has to be something that concerns them enough to warrant a lawsuit. It's unlikely that Ubisoft will take any action over a couple of models. And there are many examples on the internet of assets from one game being used in other games, and these games are often less related to each other than Heroes 5, 6, and 7. In general, it's a gray area; it seems like you can do it, but maybe you can't. That is, Ubisoft always has the option to take action, but the question is whether they want to, especially considering their level of interest in the Heroes series. Even regarding Heroes 6, it's not entirely clear. It seems that it was said that assets from Heroes 6 can be used for Heroes 5. But who gave this permission? And is there any guarantee that this permission has any legal force, or is it just something that will be forgotten in the event of a dispute? Ideally, of course, it would be great and more interesting to do everything from scratch, not to use assets from Heroes 6, 7, etc., but to reach that level ourselves. But firstly, this is much less in demand because most people want to see "how it looks," and secondly, it's much more difficult and time-consuming.
