Qestion in color of fbx exporting

[eric]

Hi,I have a qestion in exporting my fbx file.
When I export my cloud point as a fbx file, it cannot shows its color in another application software(unreal engine ,blender), only can show in CC.
Here is my mesh building method:
1. I import my txt file with RGB data (x,y,z ,r,g,b)
2. I use Delaunay 2.5D to build mesh
3. I save this mesh as a fbx file and export to my source folder
Is there another to export my fbx file to make my fbx file bring RGB attribute?

I guess it's because not a lot of applications are managing per-vertex RGB color properly? Most might expect textures?
