Vertex stuck on another object

[Deleted4363562User]

So, I made an outfit with the ubiquitous postman bag we all see nowadays. I have spent hours in OS trying to minimize clipping. I finally get something acceptable and low and behold...one of the bag's vertices seems to be attached to the pants somehow so whenever the Character walks or jogs, you can see it pull the bag's texture and mesh towards the body. I have no clue how this happened, but everything looks absolutely fine when standing still.

It's probably heavily weighted to one of the leg bones. Select the mesh, then select the bones tab and scroll down to where you start seeing leg bones, then see if any of them have higher weight (warmer color) set for that vertex. You can either remove that weight entirely from it, or carefully reduce it to match the surrounding weights. Either way, use a small brush at a low strength and only alt-click on that vertex (or mask out the surrounding ones so it doesn't matter if you misclick). You may also need to check all the other weights to see if it has lower weights to other bones than its neighbors.

 

If it's a weight you accidentally messed up by misclicking during earlier edits, you can just load the original mesh as the reference and copy weights from it.

Well, it's happening even when I use a fresh mesh without any editing. I honestly don't know how to check bone data or use the weight brush in OS. I'm very new to the Program. I've been looking for a tutorial on that.

Here's some pics. I'll try to check the weights again.

EDIT: Wait.... gah nevermind. I thought that one had cloth physics but on checking, it doesn't. Does OS complain about missing bones at all?

Nah, not at all. I'm getting ready to maybe delete everything and start over. Not sure what else to do. The darkest color the weights how up on the bag is green, and if I move the preview sliders none of them distort the mesh in the same direction as what happens in-game.

Sorry to bump this again.

 

At this point though, I am fairly certain that this is a weight problem. I fiddled with the weights for the RButtFat_skin, Pelvis_Rear_skin and the RLeg_Thigh_skin. This seems to partially fix the issue, so I feel more confident about how to fix it. However, I don't properly understand the weights and how to lower them in OS.

 

If anyone can explain it, or point me to a tutorial, I would appreciate it. I've read through the OS Nexus page, and have either missed what I need to understand or...well, I don't know.

Ok...I think I got it finally. I still don't really understand weighting, but I pretty much deleted all the weights for everything on the back of the bag except the Spine and it looks and acts fine now.

Just came back to say that this seems to be a problem with Outfit Studio messing with some weights. It happens on more than one outfit.

 

Bodyslide in general seems to reset weights on the postman bag every time you rebuild the nif.

Having just had to fix rigging on a mesh myself I can at least tell you it is definitely OS being odd about how it copies weights. If there are weighted portions of a mesh really close together (Such as, say, stuff on the belt rigged to the Spine that is also very close to stuff rigged to the stomach fat bones) it will copy the correct weights (1.0 to Spine1_skin), but also throw in some weights from those other vertices snuggling close. I can easily see how this happens with the Postman Bag. You have to go through each time and get rid of the extra weights.

 

Easiest way I've found to do that, is set your brush size, strength, and focus to max. With your shape to edit selected, go through the Bones list and when you see weights on that shape that don't belong there, alt+click and drag with the weight painting brush and it should just remove them all. Obviously this doesn't help when you just need to reduce a weight without removing it entirely, but that's a whole different set of stuff to learn. On something where you might accidentally nuke weights from stuff nearby that actually need them, just reduce the brush size and be more careful with your aim.
