Exporting Vertex color when using VAT

I've got a fluid sim set up in Houdini that I've succesfully brought into UE4 using Vertex animation textures. When importing the resulting .FBX into UE4 I noticed that all Vertex colors are completely white despite having set custom values for them inside of Houdini. At first I assumed Houdini didn't export Vertex colors, but when I tried exporing a single frame of my sim as an .FBX using the ROP FBX Output node all my vertex color data came through like I wanted. Does the VAT export get rid of vertex color when exporting?

米克林顿·塞西Run into the same problem.How to export the Colormap of VAT is there any reference?Thanks.
If you’re exporting a fluid sim, the point count changes every frame. So the exporter creates a set of triangles with a constant colour. You need to export the colour texture to capture the vertex colour.
I'm using Uniy
