Can you convert an armature animation/simulation into a vertex animation?

Title says it all.

Try exporting the mesh to an MDD file (you may need to enable the MDD exporter in the Prefs) then re-import it as an MDD file to a mesh with an IDENTICAL vertex layout/count (basically your original mesh without all the armatures etc). Keep an eye on any subsurfs and decide if you want them applied to the MDD or if you want to use the modifier downstream.

MDD importer will create a series of Shapekeys that will mimic the animation perfectly (in my experience, at least).

Thanks dude!
