I am very new to blender and now working on attempting to recreate the Odyssey Aatrox Sword. I am satisfied with the work I have done with the modeling, although it is far from perfect but, I have been struggling to recreate the material of the blade. Below are images of the sword reference images that I am working off. I am wondering how people much more experienced than me would try to recreate the gradients and smaller details.
