MASH explode to alembic, with motion blur

[a.mayaUser]

Hi everyone,

I have this mesh that uses the explode node in the MASH network, and I need to cache it out using alembic.

Usually I create a colorSet for the velocity, and then tell the alembic exporter to write that colorSet and everything works right in the render.

But with the explode node this procedure is broken and for some reason the colorSet is not exported.

Any idea how to solve?

Thanks!
