Fitted mesh problem

[MilaChristensen]

Hello to everyone

I have two problems and I hope to find a solution for them
I am new to rigging and I face two problems  in fitted mesh as follows:

the first problem shown in this  picture , the hair is of my design in the picture  2 shown in my ad the hair is normal a bit long but  in the picture 1 appears very short in length
of course the shapes are different and i'm not expecting  a big similarity but there is a large difference between them.

I'm using mayastar for rigging and my setting are :

bind method:closet distance

skinning method:classic linear

normalize weight:post

max influence:8

Dropoff rate :5

 

 

the second problem is follow:

 

The second problem is similar to the first but somewhat strange

the hair in picture 4 appear different from the image in maya ,when i try others hairs from others creators with the same shape they have no problem, but i have

in your opinion why i have that difference?

 

any advice will be appreciated ..thank you so much

All settings are good, except for the Max Influences: SL caps them to max 4, so there-s no point in having them higher than that. Deformations results would be biased by the capping once uploaded, also.

About the discrepancies:

Case 1 is most likely due to the automatic capping to 4 influences, therefore having some weights removed might just give out that result.

Case 2 instead seems normal to me.

See how your shape is consistently narrower inworld than the default avatar in Maya. Wear a newly created shape and make the comparison with that and see.

Rigged meshs are scaled according to bone length, a shorter and narrower avatar will lead to a shorter and narrower mesh.

Does mayastar allows you to work using your own body shape at all?

Yes, but not as Avastar does. It doesn't read your avatar XML file, the shape can only be accomplished manually through sliders.

This is not entirely accurate: the mesh follows the bone scale, for narrower shapes the bones scale side-by-side also, in a non-uniform fashion.

Correct. I should have specified that.

I went down to the 4 influences ,it seem that look ok now testing in beta grid

Incorrect. It doesn't load a file with your body shape, but you can definitely make your own shape adjusting the sliders to match those of your inworld avatar

do you mean that i can use my own .. but i have to bind it with skeleton?

To get the same exact look you're after for your own avatar, yes. Maya supports custom bind poses, and a shape falls within the definition of bind pose. So if you make a replica of your avatar shape on Maya and bind your mesh to it, you'll get the mesh to look exactly as you designed it in Maya on your avatar inworld.
