Roughness map not showing up correctly in Blender (Cycles)

[RandomLobster]

Hello guys !

I'm fairly new to Substance Designer, it's been less than 2 months that I started using it. For one of my projects, I created a roughness map with a lot of dirtiness but I can't seem to find why it doesn't show up in Cycles. As you can see, it kind of show up in Look Dev, but it's just flat in Cycles. Does someone have have an idea how to correct that ? Thanks !

Oh and the first screen is Substance Designer, the second screen is Cycles and the last screen is LookDev.

The roughness map will only set which areas are shiny or matt. Have you set the lighting in cycles to give the shiny areas something to reflect?

Hello ! 

Yes, I played with different lightning but it didn't change anything, but today I imported my material to a new blender file and it's working so my problem is solved ! I may have done a mistake somewhere yesterday. Thanks for the reply however !

No problem. Glad to hear it is working.
