Phoenix Vision – a comprehensive modification of the game’s visual aspects.

What was wrong with the previous helmet model?

It's just that at some point, I realized that I liked the original helmet model more. That's why I gave the creatures back the helmet that was rightfully theirs.

Author, please tell me, do you know which parameter can be used to increase the size of a creature model? And is it even possible? I'm working on a global mod for Heroes 5, which I will publish here as soon as it's ready. You somehow made the scouts the same height as the others, so you must know where these parameters are. I need to increase the size of the Biara slightly; this is for the female characters of the Inferno faction. Thank you.

It's best to ask such questions in the modding FAQ section or in a private message.
You can only adjust the size of effects using the xdb parameters.
The size of static objects is determined by the geometry, and the size of moving objects is determined by the idle00/attack01/happy/death animations, etc. In the case of Biara, you need to edit the animations, but you can't do without certain skills in 3D modeling.
