The AnimToTexture plugin is a pretty amazing plugin that allows developers to convert their skeletal mesh bone-animations to vertex animated static meshes via texture data. This offsets some of the heavy lifting from the game thread to the GPU and is much cheaper.
I've taken some time to try to automate the process as much as possible, though users are still required to manually add the material layer attributes setup to the parent material before the baking process can begin. I'm looking into using a python script to automate that (eventually).
