How to Import .OBJ with colors stored per vertex

This website http://cvl-demos.cs.nott.ac.uk/vrn/ lets you create a 3D mesh from a 2D picture which you can download in .OBJ with colors stored per vertex.

Meshalab renders it perfectly but once I import it into UE4.19 I get just a graycolored image.

I tried exporting the mesh into .ply from meshlab, open in it blender and set up some nodes with Cycles. I can get the colors showing, but exporting it into .fbx and importing it into UE does not work (meaning still no colors).

Anyone knows how to properly import an OBJ with colors stored per vertex?

I just posted an answer in this thread. https://answers.unrealengine.com/questions/831291/view.html
