[SOLVED] Meshgroups are missing in game

Hi. The dress must be split in meshgroups in the end, after all other issues are fixed.

That said, your dress does not need to be split the same way the reference is. The reference is split at the bottom to hide boots. Your dress must not do it because there is a cut on the side.
Hiding sleeves and necklaces is optional.

- join all meshgroups into one, remove doubles;
- give it 0000;
- delete all vertex groups from the dress;
- clone yfBody_DressMaxi, export the blend, append in the scene with your dress, join into one, rename to Reference;
- transfer everything;
- clone dresspanels, import the dress there

Yes, but it is best to stick to similarity. For example, a dress is more likely to be affected by the same bones as another dress, as opposed to a swimsuit. So if you’re making a dress, choose another dress made of one meshgroup. But if the limit is exceeded (as in, your dress must be affected by skirt, foot, toe bones), then you will have no choice but to split it

Well, there may be some minor issues, but you don’t have to re-do things, just replace the body.
Next time, before re-transferring things, separate the dress from the garment.

Of course, you can do it endlessly. The reason you want to delete weights is the 60 limit. If they add up, the limit may be exceeded.

You should consider the type of the bottom (skirt or « legs », basically, whether there is a split in this area) and the length of it. It would be best to choose references with as little sculpted details as possible (because the garment is split along them, which results in ripped uv_1). Everything else is irrelevant. It does not matter if it’s nude arms or sleeves. There is a minor difference in the groin area of pants and nude/underwear, but it’s insignificant, so it doesn’t matter if it’s nude legs or pants either. Skirts matter, though, especially their length. 

Mmm, well, I did create a bit of a confusion in my tutorial, so let me explain a bit about this area.

So in my tutorial, we separated an area that was affected by a specific vertex group. The only reason for this was the exceeded bone limit (presumably).
Now look at this picture:

When pants are paired with boots, the boots clip into the pants.
To avoid this, boots and pants are split the same way, in the same locations. These overlapping areas belong to the same regions, but have different layers. So if pants need to tuck into boots, their meshgroups have lower layers than boots. If they need to hide boots, they have higher ones.

Same situation with dresses. When a sim walks, there’s a chance that boots would clip into a skirt. To avoid this, the bottom of the skirt and boots are split in the same places as well, and meshgroups of a dress hide corresponding meshgroups of boots.

Anyway, if your dress were not cut on the sides, you’d just separate it the same way the reference dress was.
If your dress was long enough to be affected by foot and toe bones, you’d have to split it for this reason (bone limit exceeded).
if your dress was not cut on the sides AND was affected by foot and toe bones, then splitting it like the reference would resolve both problems 

The clipping is not a big deal though, at least I have options. But why does the dress rips at the mesh area? It appears when I play with the sliders and looks like the main part of the dress is able to stretch, while the lower part is unable to stretch lol.

Hm, okay, either this is a bug with s4s or they changed vertex paint hex codes for the 366478th time again. I'll ask Andrew about it
Well, this just proves that you should always just transfer everything without a second thought.
Anyway, deformation maps used in morphing come in two versions: skintight and robe-like. One is meant for skirts ( and between the breasts on loose clothing but, as you see now, it looks like a bra ), another one is meant for everything else

This is an example for hair, works the same with clothing

Alright, so what should I do with it?
