Shoe Conversion Help

Hi. You need to disable Limit selection to visible to select the whole shoe.

Limit selection to visible is a name of a button that is located in the bottom right corner in the picture above
You need to disable it before selecting the mesh

You duplicated this mesh the wrong way and now have overlapping meshes. Since rigging and morphing were not re-made, shoes do not stay in one place in-game and you can see that they overlap

Basically, everything should be re-made from the start
- put the original un-edited package of shoes for children in both C:\Users\---\Documents\Electronic Arts\The Sims 4\Mods and C:\Users\---\Documents\Sims 4 Studio\Mods;
- close s4s if opened, open again;
- Create CAS standalone, click CAS, filter by Custom. Shift-select on one swatch to select all, save the new file in C:\Users\---\Documents\Electronic Arts\The Sims 4\Mods;
- switch to Categories tab, change the tag from Child to Female, Apply to all swatches;
- export LOD 0, naming it original.blend;
- clone yfShoes_PumpsHighPointed, export LOD 0, open;
- File - Append - original.blend - Object - s4studio_mesh_1, append;
- select s4studio_mesh_1.001, switch to Edit mode, in UV editor enable sync, press B, select this uv island, in 3d view press Delete, choose Faces;

- change pivot to 3d cursor and disable Limit selection to visible;
- switch to orthographic ( NUM5 ) side ( NUM3) view;
- select everything with A, press G Z, move them up until they are on the line;
- press S, scale the shoes until they fit;

- switch to the front view ( NUM1), press B and select only the right side. Press G X and move until they fit;
- copy this value;

- press Ctrl I to invert selection, press G X, move a bit, then replace the value in this field with the copied one but without -;
- select the maxis shoes, then Shift-select cc, in 3d view press Ctrl J to join;
