HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Is it possible to implement the generation of mirrored templates in SoD? I would really like that.

Mirrored templates cannot be created in SoD. In HD, they can. But I won't get around to this in the foreseeable future.

Currently testing HD beta 11 + VT. Protected saves also work in VT.
