Current questions and answers regarding the map editor.

RedHeavenHero, where should I copy the texts? And will I be able to assign special properties to it (avatar, biography, name, texture)? Thank you very much for the script!

Unpack the texts and copy them to map_name.h5m/Maps/Multiplayer/map_name/.
You can assign special properties in its Shared. Or even through the tree/hero properties panel. You can re-skin an old hero (by changing the portrait, name, biography) or create a new one. I'll say right away that I can't help you create something radically new, as I haven't seen 3D modeling in a long time.

By the way, what is meant by the word texture?

By the way, in that script, you need to
for i=1,5 do
replace with
for i=1,slots.n do
