I have followed a tutorial with the image below which I used for a Widget but for something that has different UVs it’s just a mess. My question is, can I convert it for a cube with rounded edges?

Hey, do you want to apply it specifically to this cube, or are you looking for a general approach of how to make edges glow?
For the later, you can look for some “Edge Detection” Tutorials such as this or this one.
Not to the default cube no, I have one with rounded edges. Will have a look at edge detection thanks.
I found a workaround, make all sides cover the same area on a separate UV.
