Issues

VAT baking output invalid textures and geometry

Caused by:

Solution:
Place DOP Network under Geometry node.

Do not include the vertex attribute “uv2”

Vertex Animation Textures node rendering error:

Do not include the vertex attribute "uv2", "uv3", or "uv4" for Rigid-Body Dynamics (Rigid) mode. They will be overwritten.

Solution:
Delete others UV shell, keep only one UV shell.

You’d better adjust model with only one UV shell by merging vertex instead of combining mesh in Maya, otherwise vertex animation would not work properly.
