The way I am making metallic maps is

  1. I put the UV layout in Photoshop.
  2. Decide which portion is more metallic and which portion is less or non metallic.
  3. Then I put colors over the layout according to the metallic color value of that portion. I choose the colors from the unity albedo color chart.

Is there a better method for creating a metallic map?

  • \$\begingroup\$ Is there an aspect of your current workflow that you're unsatisfied with? Some specific kind of output you don't know how to produce, or a particular step you'd like to streamline? \$\endgroup\$ – DMGregory Aug 22 '18 at 18:54
  • \$\begingroup\$ @DMGregory Actually I am confused or, I just don't know how do I create a metallic map. I use only Photoshop and crazy bump for texturing purpose. \$\endgroup\$ – Mr. Bhaskar Aug 22 '18 at 18:57
  • \$\begingroup\$ The steps you described above: do they work for you? Does it successfully produce the metallic map that you wanted? If not, how does it differ from what you want? \$\endgroup\$ – DMGregory Aug 22 '18 at 19:38
  • \$\begingroup\$ No, it turns out useless. After seeing an example of a metallic map somewhere in unity documentation, I thought, maybe this maps are created by putting black color on the UV layout where there is no metallic thing, and a range of white and black colors according to the metalllicness of that portion. That's why I started doing this in Photoshop. But that doesn't seem to be the correct method as it's not showing any result. So, I desparately want to to know the correct method of creating metallic maps. \$\endgroup\$ – Mr. Bhaskar Aug 23 '18 at 4:09
