Replacing vertex color doesn't show the same results

Hello everyone;

A little problem here. I created a simple object in Maya (just a plane with some subdivisions) and then I painted some colors and created a black and white gradient.

I exported the mesh and then I imported to Unreal with Replace to see my Vertex Colors from the FBX, but the results are different:

I am using the version 4.18. Someone could help me, please?

Thank you in advance!

I will attach the FBX here so maybe the problem is inside mesh and I don’t find it. link text

Sorry, but I having the same problem with vertex colors. I would need some help to understand why the mesh can not show the vertex colors properly.

Any help would be appreciated!
