How do I unwrap bevels properly? (For use in UE4)


I’m stumbled in a problem where bevels can make textures to get stretched in UE4. I am aware that the UV is so small that probably it creates problem, not sure either.
I’m just wondering in general, what is the best practice to unwrap the UV this tiny bevels like this? Do I have to do it manually one by one, enlarge them or forth? or is there a better way to do it?

Here is the example:

Nevermind, got the answer. I reduce the Unwrap margin even further to around 0.01 and it works fine. I was trying to give spaces between the UV islands cause I heard small margins can give problems, but I didn’t optimize which margin is correct in my situation.
