Hi when i bring my blender file into unity , i will attach the texture maps as follow :

diffuse/color map --> albedo

normal --> normal

roughness --> ?

specular --> ?

displace ---> ?

metalness --> metalic ?

Some doesn't have the matches. How am i suppose to do with those maps  ?

When I bring my Blender file into Unity, I will attach the texture maps from my Blender material (left) to the Unity material (right) as follows:

• diffuse/color map --> albedo

• normal --> normal

• roughness --> ?

• specular --> ?

• displace ---> ?

• metalness --> metalic ?

I haven't found matches for the roughness, specular, or displacement maps. What should I do with those maps?
