Vrmesh/Proxy color set problem

V-Ray V-Ray for Maya General

im trying to get bifrost to render in vray, i am following all the documentation on the website ( Chaos Docs ) and its working great.
It renders great, and has great motion blur.

HOWEVER when i try and link the velocity colorset (colorset0) i get solid black. what gives?
If i try and connect the velocity colorset from the original alembic it works great. just not from the vrmesh.

clearly the vrmesh has this colorset information since its rendering the motion blur beautifully, so why cant i connect colorset to anything
once its a vrmesh?

Do you have “Export Vertex Colors” on? Since the velocity must be exported 2 times I think for vrmesh - as a velocity vector, and as a velocity color set.

that was it. That should be in the documentation. Thank you!
