Change fonts

How do you change the fonts of VCMI ? I tried to change the fonts in the .lod files in the data folder but it’s still isn’t working.

Changing fonts in vcmi is easy - the best way is to make a mod. Here’s for example mod with HotA fonts.
Of course you must disable True Type Fonts mod to avoid conficts.
If you explore this mod you notice that making mod with fonts as .fnt files is childish, if you have to make mod with fonts as .ttf files is a bit harder, but only a bit ;]
