Weight map issue or not?

felis

In another thread I read that the dress Lucid Dream had a problem when posing, but they had made a service ticket (I can't find that thread now).

I was curious and as I had the dress I could confirm that when posed it had some weird artifacts.

Trying to understand how things are working, my evaluation was that it must be a problem with the weight mapping, and I thought it could be fixed by smoothing the weight maps for the relevant bone(s). After some investigation I found that at least bending the leg causes the problem.

I have attached 2 pictures, one is in zero position, and the other is with right leg bend around 90 degree. On the pictures can be seen the artifacts in the right side of the dress, as well as some weird stretching over the stomach.

But trying to smooth the area didn't solve the problem. And my guess was that it was just some vertices which had a different weights, but that doesn't seem to be the case. So now I am wondering what actually is causing the problem and thereby also how to solve it - not that I intend to solve it (I will leave that to the PA ), but to understand if I in other situations experience something similar.

So can anybody explain what is causing this problem?

Well you see the rigging [bones] are made to move the humanoid figure, not clothing. Yes we throw the bones over to the clothing so they will fit and work on the clothing but no one piece is going to work 100% at all angles of all poses no matter how extreme or unnecessary those poses are. In the body when one bone is moved it affects the other bones so that the entire body [hopefully] looks to be right.

The easiest solution IMHO for many of this little stretch details is simply to create a "little morph" [using Hexagon] to fix 'em.

Put the clothing on the figure "fit to and parented", send it over the bridge to Hexagon. In D/S select the clothing, in Hexagon morph the clothing to look better ... select the clothing send it back over the bridge to D/S and make the morph reversing the shape and making any of all the other required decisions necessary ... and then dial it in. If you like it, save it as File > support assets > morph assets with your handle as Vendor and something intelligent as Product [because these become folders]. Then it is there any time you wish to use that pose on the Parameters Tab [possibly under Morphs/Morph Loader].

Edit to add: zero morphs before saving them.
