Question about SkinMorph.

Post by alias3ds » 20 Jul 2016, 15:17

Hi There

I'm inquiring about how to do Morph with the rigging model after sculpting reference model in Mudbox and then importing back to xsi.

Because after I applied Shape Deform to rigging model, the incorret deformation appeared. See the attachment.

Any help is welcome. Thank you

Hey alias,
i think your sculpted model has already some bone deformation applied. that is not good. when you sculpt in mudbox, sculpt on the "unboned" hand. you can load a "boned" hand inside mudbox as morph target. after that you sculpt your detail. when you are finished disable the morphtarget inside mudbox, and export the sculpted "unboned" mesh. another way you can achieve your wrinkles is by using a displacement map. you can write them out of mudbox.
cheers

You can do this in Softimage too, this is usually what secondary shape mode is for. When you call "apply shape" after modeling in secondary shape mode, your tweaks will go through an "inverted envelope deform" before being stored.

One issue here is of course that you're not working in the model's operator stack, but have an outside model.

You can put it there however using ICE .. switch to secondary shape mode and create this ICE tree on the envelope deformed model

then call "store shape key" or "store and apply shape key"

Hi CYTE

Thank your very much for your reply.

I followed the first way and did some test, but some problems arose :( . See the attachment.
Am I doing something wrong? Thanks.

you're welcome glad it worked out.

btw just tried the same in Maya. It finally introduced "shape invert" in the last version too - but this operator stack trick isn't possible because it's more like a black box implementation.

So it looks like you can only invert tweaks of the model itself, not outside meshes.
