Painted foliage

Hi,

​​​​​​I have painted foliage on a mesh. I have retopo’d this mesh but, for weird reasons, UE won’t let me reimport the new version.
of course, if i delete this mesh, the foliage IS also deleted. So I’d like to know if there’s a way to keep this foliage layer ?

Regards

Well, I edited the asset in UE to a single triangle. It does the trick so far.
