[SOLVED]How to fix weights on dress w/ a bow +add underwear?

Hi. Spine bone should not be the only one affecting it. Also, you need to retransfer uv_1 because the bow's uvs are on arms as well. And the mesh is not vertex painted, so may as well transfer that
Do the following instead:
- enable sync, select some areas of body uvs, press Ctrl L to select all of it, separate with P - Selection;

- append the reference again, select arms on it, delete them fully;
- transfer weights, uv_1 and vertex paint from the reference to the dress like this. To select UVs as well, hold Shift:

- once done, join both, delete the reference

Sorry for the late reply, lost the thread

Basically, it is done this way:
- delete areas of the body covered by clothing;
- close the hole at the bottom ( quoted text only );
- connect the dress to the body to cover gaps between the two in other areas

You can put uvs there, but more free space = bigger uvs = better textures. + the body may clip into the dress in some poses

I would need to see the package files where all the textures are. In the linked screenshot, it is looks like either a shadow map or just a shadow. If you removed the shadow map, it is just a shadow


As for other issues:
- you chose a bad reference. The weights are wrong, uvs in uv_1 are stretched and vertex paint is wrong. I assume this was a cc item. If yes, never do this, always go with maxis items. Clone yfBody_Chemise and retransfer all data, do not forget to separate the body from your garment and remove arms from the reference;
- the inner side is needed only where it is visible, not everywhere. Otherwise it double the polycount. Right now your dress's polycount is 4.5 times higher than maxis most complex items. If you plan on sharing your content with others, keeping polycount low should be your number 1 priority. If your content will negatevely affect the performance or crash the game, people will delete it and never download from you again;
- when the other side is created, its uvs should be moved away from the front, otherwise there will be a conflict during texture baking;
- unless a difference in texture quality is acceptable, you should not scale uv islands individually. Buttons can be bigger for better definition, the front should not be bigger than the back;

CAS items do not interact with light sources in-game like that, this shadow is baked into skin



That is what you were meant to do, ea underwear appears only in s4s because it is a part of the avatar's skin, added for censoring purposes

this data transfer set up i gave transfers weights, uv_1 and vertex paint. Everything you've done after that was unnecessary

- delete 2.7 from your computer, you do not need it at all and should avoid tutorials where you are told to get it. This is a sign an author is a beginner who did not bother googling how to transfer weights in 2.76+ before making it;
- in the future, export the garment as weld from MD and do not lower particle distance that much;
- clone chemise, export the blend, open;
- rename the mesh to Reference, delete arms;
- import your garment. Since it was exported as unweld, weld it first with Remove doubles;

- select your garment, add data transfer, choose Reference as Source object;
- enable Vertex data, choose Vertex groups and Nearest face interpolated. This will transfer weights;
- enable Face corner data. Enable Col. This will transfer Vertex color;
- Shift-select UVs, choose uv_1 instead of All layers. This will transfer uv_1;
- because uv_1, vertex groups and vertex paint do not yet exist on your mesh, you need to click on Generate data layers. If you were overwriting this data instead like before, you woudn't need to do this;
- Apply;
- switch to Edit mode, select everything with A, Clean with All groups, Limit total to 4;

- switch to Data tab, check if vertex groups appeared in the list, if there is Col and uv_1. Now just rename UV map to uv_0 and that's all, the garment moves and morphs as it should;

- close holes, unwrap created geometry ( this step can be done later, after you join the body with the garment );
- you can append a lingerie set, but the nude body is already in the scene, so you can use it instead. Expand the rig, make top and bottom visible and selectable;
- select top, in 3d view press Shift D, then Esc to duplicate it. Do the same with bottom. Select top.001, Shift-select bottom.001, join with Ctrl J, optionally rename to Body;

- select Body, switch to Edit mode, select everything, Remove doubles with merge distance set to 0.0001;
- disable Limit selection to visible, select all areas of the body covered by clothing, delete. Now the body is ready;

- select the garment again, select all uvs in uv_0, assign a template, shrink them with S Y 0.5;
- important order: select the body, Shift-select the garment, join. If you will do this in a different order, the item will be parented to the rig and the game might crash. If you are using an appended body, the order does not matter;
- once everything is unwrrapped, put it into free space. Remember, bigger uvs = better texture. If you cant cram uvs into the torso and arm areas, go for the extra space;
- split sharp edges;
- give it cut 0000, import back into the chemise package

Ah, i understood why this happens. See how there are legs under the skirt on the reference? They are closer to your garment than the skirt, so it is taking data from them.




You removed doubles on the body because it has no sharp edges, nothing should be shaded as sharp on it. This should not happen on the body

Your dress would have had sharp edges if you closed holes. Since you did not do that, there are no sharp edges to split.
Here is a difference in shading between split and non-split sharp edges.


You've already assigned the template to the background in uv_0

- separate your garment from the body;
- delete legs, arms and geometry that cover the hole at the bottom of the chemise;
- transfer vertex groups and uv_1 again, no need to click on Generate data;
- Clean and limit total;
- there is no need in closing holes on the body, they arent visible, just delete that geometry you created;

- when baking textures, disable rendering for the reference and body parts under the rig. These big back blotches happen because of that
