Convert none Unity PBR textures to Unity

[AndersMalmgren]

Is there any article about this?

I simply copied the Roughness map into the alpha of the Metalic map but I do not know if its correct, I think the result looks a bit funny

Here are the maps

Here is picture from Turbosquod

From inside Unity

Something is off, is it the normal map or something?

Unity uses smoothness rather than roughness. Invert the roughness.

You mean reverting it before pasting into the alpha? I did that but didnt like the result. What I did now was to revert the green channel of the normal after reading on the net. It seems to make it alot better

Not inverted roughness

Inverted
