Does the hero also occupy 4 squares, like the large creatures? And can you import a throne into the editor for testing without a skeleton, just to see the size?
P.S. In principle, it's not that difficult to adjust the proportions.

Yes, it occupies four squares.
You can import it, but in the editor, the cells coincide with the hero's size.

If it's really necessary to load a model without a skeleton into the game, there was information about this in the psatkha tutorial. I understand that it differs from loading a model with a skeleton in point 14 - before exporting, the skeleton line is removed from the game model file.
