Generate Unique UVs Button is Missing

As the title states, I have a 20% overlap on one of my models and I would like to generate a set of unique UVs. However the button seems to be missing. Where has it gone?

Hi!

In later version of UE4 you can create unique UV, when you import static mesh, . Or in mesh editor in “Details” tab. But I recomend create secondary UV in you favorite 3D programm.

I made it and not work…

Hello -

Also after you generate your New UVs, make sure that you assign them in the LightMap Coordinate Index, shown in the picture above.
