Hero replacer.

It’s best to use DXT5 where appropriate (except for some effects and icons of units and heroes); otherwise, the textures will be too large, and the game will crash as a result. Heroes of Might and Magic V doesn’t like large files. In NVS, I try not to make textures larger than 1024x1024 pixels, and I also make sure that their file sizes are similar to the original textures. For example, if the original file weighs 1.3 MB, your file should weigh approximately the same. Use DXT5 and enable texture generation. Then, your files will be close in size to the original ones.
