This Helmet has both low and high poly, textures and it is ready for UA or Unity. It took me around 2 days to make. I hope you're gonna like it. Most of the work was made in Maya and Zbrush. It was eventually Textured in Substance Painter and Rendered in Marmoset Toolbag! Feel free to ask me any questions you want!
