Fixs_3.1 has been updated.
Unlike this mod, this fix does not affect creature or hero files. The mod is fully compatible with fan maps and mods that have modified creature and hero files. Creatures in the Sacrificial Pit are displayed correctly (second screenshot). I'm also attaching the mod separately.
p.s. didn't quite work out with the war machines.
anyway, the reason I'm writing this. Could you tell me if there are any other mods like this? Ones that make other pictures in the game less blurry WITHOUT adding anything, purely like in your mod — just fixed the .hdb icon files and that's it. No edits, no fixes, no "well, it looks better this way so I decided to add it", no improvisation of any kind whatsoever. Just fixing the .hdb files like you did. And would you be interested in trying to combine all these mods (if there are any others) into one, making a big texture pack with non-blurry pictures throughout the entire game? :D
