View smoothness instead of roughness in buffer visualization

Hey is there any way I can change the buffer visualization to show smoothness instead of roughness? In my material I have a 1- node right before my map is plugged in so I’m always working with smoothness in photoshop because I find it more intuitive but when I use the view mode in UE4, its backwards from what I’m used to seeing and working with so I was hoping there was a way that I could change that.

Thank you!

I would consider getting used to roughness, since you will be needing it a lot, and it is weird to invert a common convention.

But to answer the question: I think for the buffer visualization you need to dive in c++. You could also make a custom post process material and use the scene texture node → roughness, invert it, and plug it in as your final output. But like I said before, getting used to roughness is the better option.

I agree here that you should try to get used to roughness. I feel like using the 1- workflow will run into some issues with compression and gamma/sRGB maybe getting in the way of the desired look.
