Parenting with automatic weights generates empty vertex groups I created a character mesh using the manuel bastioni, and then wanted to use the rig created by rigify. I followed the steps as in this video:

When I parent the character mesh to the rig, there are a bunch of vertex groups created. But, when I click on any of them and click "select" in edit mode, no vertices are selected. This also means that the rig is not really skinned - no vertex moves along with the rig. I have looked online for other's having a similar issue, and none of those apply to this case (for e.g., scale transform is applied before parenting).

Here is a google drive to the blend file, saved right after I did the parenting. The metarig is present but hidden, in case you want try regenerating the rigify rig. What is going wrong?

Hey I just got the same problem with the ManuelBastioniLAB Addon and what seems to work for me is the following:

So do you remember that you have to check your mesh, that had to be only close mesh with no additional objects like the eye balls and teeth... well after i spitted and isolated the body I deleted the double vertex by getting to edit mode, select all the vertices, press W+Remove double vertex BUT changing the "merge distance" to 0.0400 or any slightly higher value instead of the default one, for some reason double vertices used for the edge split to fix edges normals on a smooth surface are not as close as they have for the default "delete double vertex" function to do the job.

Hope that works for you! It took me a long time to find out!
