Blender fbx export with custom properties to be read in UE ?

another caveman

Hi!
If I give custom properties like such to meshes, and export  as .fbx, how could I  read them back in UE ?
If not possible through those, how would you pass some floats along with a mesh .fbx ? I was thinking there could be trickery with UVs but that's some setup.
I already need to make use of vertex color for other content..
Maybe a color in Material to be exported could work out for it.
It'd be neat have those custom properties follow along and readable in engine

im fairly sure you'd have to make edits to the fbx import to read any custom stuff you hide in the file.  the options just aren't there in the importer. 

you could dump the data to a CSV and import it to a datatable or if it's per vert just encode it in vertex color or UVs

Ah, too bad! Thanks for the information.
I'm already using vert color, but maybe a simple way could be to give a material I won't use in engine but that still carries the informations in color

I have not tried it but here are some docs :

Not sure if the blender fbx exporter writes out the attributes in the expected way tho..
