Texture won't show up in S4S

I used blender 2.70 and 2.78.
And because I don't have the option "create a 3D mesh" I clicked on "Create a CAS Standalone" on S4S.

Hi. How come you do not have Create 3D mesh option? Could you show a screenshot of The Sims 4 starting window?
Create a CAS Standalone is for creating recolors.
Please provide package and blend files for further assistance

My apologies, I wasn't aware about this change, good to know



Anyway, there's a lot wrong here.

1). The sims 4 studio imports only those meshgroups in the blend file that have a cut number assigned to them. If multiple meshgroups have the same cut numbers, s4s will import only one, not necessary the one you want. You have a reference in the scene that has the same cut number as your garment. S4S imported the right one, but it may not always be this way, so either remove a cut number of the reference before importing the blend file or just delete the whole thing;
2). Each meshgroup must have 2 uv maps. The first one, uv_0, defines how the texture will be projected on a 3d model. The second one, uv_1, dictates how the mesh will morph during body customization. When you join two meshgroups that have the same number of uv maps with the same names, the uv maps will be joined a well.
Your item has 3 uv maps because you joined the body with 2 uv maps and the garment with one and a different name. This is the reason why your uv islands do not align with the textures.
3). You should never join the body with the garment until you make the later functional ( uvs, vertex paint, weights). You should never transfer weights or uvs to something with fingers because it will never turn out right ( unless you know how to make it turn out right which is worth the hustle only when making gloves);
4). When placing uvs in the uv_0 map, avoid that bottom right corner like a plague because everyone puts everything there and you end up with CAS full of items that cannot be used with each other because their textures overlap. These uv islands should be crammed where you deleted areas of the body hidden by clothing. Also, in Marvelous Designer the uv space is square while The Sims 4 textures are rectangular. When you use uvs generated in square space with rectangular textures, they get stretched vertically. So before placing them in the right spot, set the background image first and scale them with G Y 0.5;
5). When you create new geometry ( like when you close holes), unwrap it;
6). The reason the author of the tutorial used 2 version of Blender was because they did not know how to vertex paint and transfer weights in the newer versions. You did the later in the newer version but the wrong way. If you have already transferred weights, they did not transfer at all.

How to transfer weights in Blender 2.78
- Make sure both your garment and the reference are visible and selectable;
- Select the reference mesh, Shift-select your item, switch to Weight paint, choose Transfer weights, choose By name;
- Choose Clean tool, scroll up, choose All groups.


The difference when vertex painting between 2.7 and 2.76+ is the shading in the viewport. Either switch shading to Bounding box before sampling the color or just memorize the following: 3FFF00 is for skirt-like bottoms, 007F00 is for hair and accessories, 00FF00 is for everything else.

These are the settings you should use when transferring a uv_1 map


7). Never use Make blank button, it does not make textures blank, it removes the file
8). Do not clone nude meshes to start your package. They have a "naked" tag that gives sims embarrassed moodlet. You can remove it in the warehouse but it's easier to just choose something else;
