Hey guys, I'd like to know where do I have to insert both roughness and metalness maps in the standard shader in unity ?

    Hi,

    There you have the standard material:

    The metalness is the metallic line.
    For the roughness, you have to put it in the alpha channel of your metalness, like alpha in your albedo for transparency.

    Exactly!
    Just under the "Channels" tab : 

    After that you just have to copy/paste your roughness.
    Make sure when you will save you keep your alpha, with png or tga.
    When imported in Unity, check if your import settings from the texture are " Alpha Source : Input Texture Alpha". You can verify your alpha in the preview by clicking here:

    Thanks very much my friend you are a life saver. 

    I found that "input texture alpha " didn't work well so I changed it to "from gray scale" and it is good
