This is the reason why I included our own list of settings for HD Mod in v0.8.1.
For you, there are two notes.
1. Read the thread
, for Enroth's sake. Carefully. Not like you read the installation instructions about the Fix.Cosmetic tweak.
2. Install H3SW v0.8.1
, for Enroth's sake. You can even limit yourself to paragraph 2, because there is no need to write tweaks in HD Mod starting from v0.8.1.
To do that correctly, I recommend deinstalling HD Mod from the game folder (using HD Mod uninstall) and deleting manually the Mods folder from your Heroes 3 directory. After that, install H3SW v0.8.1 according to the instruction.
If you still want to use HD Mod, you can also install it following to the new instruction in v0.8.1 thread.
