Alpha Parts Don't Move With The Body

[_SoNaRiSa_]

Hi!
I have a problem with the alpha parts. I use milkshape and i use "plane" section to draw alpha parts. it looks so normal when mesh finish, but when sim move it looks weird because alpha part don't move with the body. it walks with the sim but when sim turn right or left it looks strange.. i don't know how can i fix this problem.. what can i do? i hope i can explain and you can help me.. thanks..

You have the bone assignments or skin weighting wrong. The upper half of the alpha should probably be assigned to spine2, and the lowest part to spine0. You have to look at what the underlying body mesh group at the same points the alpha touchs is assigned as, and match the assignments and weighting in your alpha part.

Yes.
A tough one in my opinion to fix.

If you select the verticies of the alpha and go into Sims2 Unimesh bone tool you will see the bone weights at 100 -1 no joint.

The skinweights should relate to the areas the body the alpha is at.

I don't personally know an easy way of figuring this one out.

For me it's copying the skinweights of the body then tweaking them until they don't clip when moving with the body.

Unless you can find a very similar mesh which does work and copy the skin weights from that mesh.

a quick way to fix this......depends if the alpha part is a copy of the body and edited.
If so, i would regroup the alpha part(prolly is already) and delete the rest, then save/ export it as a obj file.
re open the original mesh and snapped the whole alpha back on the body with Wes H his data merge tool so every vert gets his bones back.
Delete the body and save as a objx file.
Import the obj alpha file and import the objx file and then import the body from the original mesh. :D

edit,
guess not....just read she made the alpha from scratch.
so much work done while it is so easy to copy the body, scale it a bit bigger and voila, there is your alpha.

I'm no expert, but what you could do is remove that top, troublesome part of the dress and make the bottom part cover more of the chest area and it would still be a good dress... Just without the bit at the top... :)

thats not a option. ;)
wat makes the mesh special is the alpha top.
