[Bf-committers] New Modifier : Morph Target

[Daniel Salazar - patazstudio.com]

Hi Kursad and others, MTM does sound great and I have often wanted
morphing capabilities in the modifier stack, however what about moving
the shapekey system into the modifier stack instead and expanding it
to support linking to other mesh datablocks? It just feels strange
having two layers of deformations that do almost the same thing.

best regards,

If you are asking if one could morph the subdivided states (ie mtm after subd mod literally), in a way yes. The idea works because I have actually tested it as an interesting case. The other side of the coin is that  it does not work because it works based on the original vertex count so morphing happens only every other vertex (subd 1). That is how the subdivision works, initially adding new details in between vertices. Basically you get a spikey version of the morph atm.
