Tool: Vertex Re-Order
Go ahead, combine & separate that mesh!
It is late and your morph target is imploding. 'Not this again.' Everytime this happens, you scramble through the internet to see if there is a way to rescue your '_v34finalFinal' mesh. You shake your fist at Autodesk and wonder why there isn't a button to fix this already.
Well look no more! I developed this tool for just this - align your vertex order so the morph target builds happily once more.
2018 UPDATE! Backed by popular demand, this tool has been re-written from the ground up as a Maya plug-in for ease of installation!
Use Maya's plug-in manager to browse and load this plug-in!
