Importing Alembic to Blender problem

Hi, anyone have experience with exporting alembic mesh to Blender? I am trying to bring a mesh from Mocha but when I bring the Alembic file to Blender the thing is not a mesh but separate vertices. After looking in the Blendermanual it seems that Alembic files have to come with ‘Transform Cashe’ constrain and a ‘Mesh sequence Cashe’ modifier for each vertex so it can transform it to mesh I guess, but in my case the vertices come only with a ’ Transform Cashe’ constrain.

Any suggestion what maybe I am doing wrong or how can I fix it. Thanks.
