Question about SkinMorph.

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
Alias

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.

Hi rr
How are you doing?
Last time you taught me how to solve the incorret deformation when applied Shape Deform to rigging model. It worked perfectly. Thanks very much.
Now I meet the same problem, what was worse, my hard drive which saved the answer crashed. So I back here to see your reply. But I can't see the photo you send to you. Is there any way that you could re-send to me? Thanks a million.

Hello Alias.
Took a little forum break but doing fine, thanks! You're doing quite alright yourself?
I'll try to find the missing image -- I think I even have a faint memory about what that trick was, will write back once it comes back to me fully
Cheers

Ah ok I remember the trick was to switch to secondary shape mode and then transfer the point positions of the sculpted target using ICE...
This would be done with an ICE tree in the deformed model secondary shape stack like this
(sculpted target --> get point positions --> switch context --> set point positions)
After that "store and apply shape key"
this should send it though the inverted envelope computation, after that you should have the base shape required and the "tweaks" (ice tree) automatically removed
