I wanted to turn the existing tanktop in the game (labelled cfTop_Underwear...00093A4 SortOrder:95), into a crop top like a bra.

My work progress went as following:
• With Sims 4 Studio, I created a new project with the CAS option, selected all colour options and saved the .package file and closed the project.
• Then I opened TSR Workshop and created a new project; Clothing > Sims 4 Clothing > Human > Child > Female > Top > cfTop_Nude. (Using default settings)
• Then I exported the four LOD meshes in .wso (Workshop object), and closed the project without saving.
• Then I started a new project in TSR Workshop; New Import, selected the .package file from Sims 4 Studio. (Using default settings)
• Then I imported the four LOD meshes, and exported the file as a .package file.
• Back in Sims 4 Studio, I reopen the project that now has the new meshes.
• I export all the textures, modify them to the new shape, and import them and everything looks fine so far in the 3D window (although that could be due to the clothes drawn on the model instead of letting the skin show through).
• I put the .package file in the mods folder for Sims 4, launch the game and the item shows up as it should, but has some graphical errors.

Issues:
- There is black artefact both on the side of the head, and around the abdomen.
Everything else works as it should.

The reason I used TSR Workshop to replace the meshes, is because Sims 4 Studio currently does not accurately export or import the meshes. It's obvious for the lowest LOD levels where the seam on the back no longer appears smooth after importing. So I will use TSR Workshop for exporting and importing meshes, and also to export swatch thumbnails which S4S does not load at all.

Hi. The artefacts you are seeing are caused by the shadow map's file format. You should export or save it as dds instead of png
Also, you are making it all so unnecessary complicated.
The reason you are seeing the seams is because you are not removing doubles before importing the mesh in S4S ( select everything with A, Tools - Remove doubles with Merge distance set to 0,0001).
S4S splits the mesh along uv island border edges to avoid shading issue. A very useful feature.
If the mesh itself is not split but uvs are, S4S splits the mesh but does not shade these split edges as sharp(Second image)
If the mesh is split, S4S shades split edges as sharp ( first image)

So it goes like this: you export a mesh that is split but split edges are not shaded as sharp, then you import the same mesh back and S4S shades those already split edges as sharp. So to avoid it you need to remove those split edges by removing doubles.

Not sure what the problem with Export swatch thing is, it works fine for me, although I do not have the latest version of S4S, can you screenshot the window please? The whole window

Was hoping I could avoid using dds. But after remaking the shadowmap after exporting in dds, and saving in dds DXT5 ARGB, the black artefacts disappeared. (I also made the shadow below the edge softer) new result, compare to previous. Thank you for letting me know what the issue was, I'm thankful for that.

I personally find your idea more unnecessary complicated. I'd rather use TSRW to just export and import meshes, than using S4S to export, modify and then import the meshes. I want an accurate export and import of the meshes, and so far TSRW does seem to do that.

I'm using "3.1.3.2 (Wishes)". Creating a new project from an existing item does not load the existing swatch thumbnails. TSRW does load the swatch thumbnails, but cannot create a .package file with working swatch thumbnails. So I have to export those from TSRW to import in S4S, which will make them show up in the game.

S4S exports meshes accurately. It does what it is programmed to do and is beneficial for creators. If it did not split the mesh automatically, there would be dark shadows like this:

Creators would have to remove them manually by splitting all edge loops meant to be sharp themselves.
If you are not exporting the blend file to edit it in Blender, then why are you doing it? The package file already has all of them.
If you cloned, say, a t-shirt with protruding sleeves but want your item to not have said sleeves, just export all textures, clone a nude top or something like this, import textures in it, and that's all. All LODs are already in the package if you are choosing Create 3d mesh.

I misunderstood you the first time, thought the buttons were missing. Hm, I've never actually noticed that the original thumbnails are not available. Googled and did not find anyone else asking about it or mentioning it. Tuning - Embed all external referenced resources did not bring them in, so it must really be impossible

The how come when I export a mesh, then import it again, it is not displayed accurately? Either the export, import or the 3D window is wrong at some stage. Exporting and importing in TSRW does display the mesh as expected.

It might be easier to edit meshes using S4S, I don't know, I haven't tried that yet. But as it currently fails at simply exporting and importing, I am reluctant to use this method as of now.

clone a nude top or something like this, import textures in it, and that's all.

An item is much more than just texture and mesh. You got all the swatches that has to be re-added, and all the category flags to set, and some swatches has different flags for some attributes. It's certainly easier to export and import 4 meshes, than it is to export 3 textures + 1 texture per swatch and import that, alongside manually noting down all the attributes.
