Does anyone know how to create creature models and add them to Heroes 5? I think Psatkha might be able to answer this question?
On my page, there is a manual on exporting from Alias Maya 6.0, and regarding creation, they can be created in anything, but then imported into Alias Maya 6.0 and exported through the game editor in Nival format.
The developers made a plugin only for Alias Maya 6.0 (there is also a plugin for 4.0 and 5.0, but the result is not always readable in the game, and it is also difficult to find these old versions).
