Oh, damn. Don't you understand that you can't just take a model from ZBrush and use it in a game?
Look. ZBrush, like any 3D sculpting program, works with a very large number of polygons with a very dense mesh. For example, when I sculpted a glove, I had about 4-5 million polygons. This is necessary for sculpting, but the game (especially Heroes) will crash if you feed it something like that. There's a good chance that Max will crash too. That's why a retopology process is needed. What is retopology? Retopology is changing the mesh, reducing the number of polygons, and then projecting the high-polygon sculpt onto this new mesh. This creates a normal map. Based on it, programs like Substance Painter draw textures, but there's still a lot of manual work involved.
