Sci-Fi Helmet

This is my personal project. I created the textures for this helmet using substance painter and mari for lookdev used houdini renderman. I learned about renderman and creating shader and linking them to houdini. Thanks to @Jahirul Amin provide me ACEScg data and did all the modeling for this by CG Cookie!
