Hi! I was just wondering how do I know which reference to pick from Sims 4 Studio? My uv_1's are always messed up even when I do the right data transfer, it always ends up messed up (jagged lines, clippings when adjusting weight, etc.) I've never been able to create a mesh that works in game. I would love to get some tips on this. Thanksss in advance. (:

I also have another problem where when I use data transfer for weights(I've tried all of the supported blender versions for Sims 4 Studio) nothing transfers (even though it did before but now it just doesn't work in any version of blender) and when I try to transfer weights through weights tools it just transfers one of the vertex groups. And I've confirmed that the issue isn't the mesh itself because I've tried other ones where it has worked before. I've managed to transfer all the data from a reference mesh in blender 3.3 but when I try to import it in Sims 4 Studio it just gives me long traceback error (I've tried reinstalling Sims 4 Studio and all the blender versions, reinstalled the addon for S4S and set the path to the right blender exe, but it still doesn't work. I feel like I've hit a wall, nothingggg is working the way it's supposed to. I've learned all the things I needed to but it just doesn't go the way it should. I really want to start making CC but nothing works.

Here is the error I get after trying to import it back to Sims 4 Studio and the blend file. drive.google.com/drive/folders/1AYeFZmTGg2B6EEC9IZFoP22m9IRR9XsD?usp=sharing

Hi.
You problem is caused not by a choice of a reference but how your garment is made.
Look through the entire maxis catalog and you will find no item with sleeves like yours. Loose sleeves receive data front the torso as well, so a portion of them stays still while the rest moves with arms.
There is always a reason why something does not exist in the catalog. If you cannot find what you have in mind, you should either modify it or not make it at all, otherwise you'll set yourself on problems.

The garments should be made to fit the body right like they do in real world. Then you will have no problems adapting it. Fortunately, one does not need to know the principles of tailoring to get there, you can just import maxis meshes in MD and modify to fit your idea better.

If your goal is to learn the basics of cc making, you should not create obstacles for yourself, just make a simple tank top for now and go back to this one later, once you know how to remake it to fit the body better.

How to choose a reference:
To behave like the area of the body it covers, your garment must receive all data from it. So if a reference contains this area, it will work.
However, there is a difference in how certain areas of clothing are meant to behave.
For example, skirts and legs behave differently, so if your garment has a skirt, the reference must have one as well, of the same length or a bit longer.
There is also a difference in how puffy and tight skirts move, so it is best to consider that as well.
There are differences in how the groin area on underwear and pants morphs, as well as the breast area on tight and loose clothing, but its pretty minor, so you can disregard it.
How a reference is shaped above the navel does not matter when it comes to rigging, but sculpted details ( collars, sleeves, layered clothing, bows, etc ) can lead to torn uv_1. The mesh is cut along them, so uvs rip as well.

The error:
At the moment 3.3 is unsupported, something broke in the plugin. Use 4.1 instead.
In your s4s settings the Blender path leads to 2.7x version while you're working in 3.3. Those are basically two different programs, so you cannot jump between them. If s4s outputs the file for 2.7x, you work there from start to finish. If you will open and save this file in Blender 3+, it wont import no matter what.
So if you want to work in a new blender, download and install 4.1, change the blender path to blender.exe in blender 4.1 installation folder, export any blend, check if s4studio mesh tools appeared. If yes, delete all other versions

Data transfer modifier problem:
Most likely you are not clicking on Generate data layers, no data is created and nothing is transferred
Weight transfer in Weight paint has different default settings, so you would need to change Active to By name for it to work.

How to make an item move and morph by transferring weights, uv_1 and vertex paint

Transfer weights, uv_1 and vertex paint with Data transfer. The result may not always be perfect, but it is best to solve problems as they come:

Unhide the reference. It must be visible* ( eye icon ) and selectable* ( cursor icon );
Select your hair;
In Modifiers tab add Data transfer modifier;
Choose Reference as Source object;
Enable Vertex data and expand it;
Enable Vertex groups*;
In Mapping choose Nearest face interpolated;
Enable and expand Face corner data;
Enable Colors*;
Shift*-click to enable UVs as well;
In Mapping choose Nearest face interpolated;
Expand UVs, choose uv_1 in Layer selection ( don't forget, otherwise uv_0 will be overwritten as well);
Click on Generate data layers*;
Apply the modifier;
In Data tab expand UV maps. Double-click on UVmap, rename it to uv_0;
If uv_1 appeared, it most likely transferred successfully;
Expand Color attributes. If you see color0, it transferred;
Expand Vertex groups. If you see names of vertex groups, they most likely transferred successfully. However, there is one ( or two ) more thing(s) you need to do;
If you're using Blender 2.76 - 2.79, 3.6.1, switch to Edit mode, select everything with A, Mesh - Weights - Clean with Subset set to All groups to fix the result of a bug that exists in these versions;
Regardless of your version of Blender, in Edit mode, with everything still selected, do Mesh - Weights - Limit total.

* Data will not transfer if you will forget to do these steps!!!

Thanks for the information! I didn't expect you to tackle all of my problems at once, and in such a short time, thank you again! I will use Blender 4.1 and make something simple. I'm usually go big or go home when it comes to things like these and end up disappointing myself but I'll go slow this time.
