You need low poly model for video games . As well as for animation too . The one hi res surface could be baked as normal map or displacement . It's not only games related actually . Nobody animates anything made of millions of polys . You can use any retopology tool if you don't like Zremesher. Blender,3d max or MAya too…
Thank you very much for taking the time to share these helpful tips gnoop . Just one last thing though, hypothetically, if was designing this guy for being used in a video game, would I definitely need to apply zremesh?
