[SOLVED] sliders don't work

Hi. While a uv_0 map projects a texture on a 3D mesh surface, a uv_1 map defines how the mesh will deform in the process of adjusting body parameters in CAS. Your garment does not have proper uvs in the uv_1 map. You should also remove every part of the body covered by the garment and place your garment's uvs there.

- select the meshgroup, switch to Edit mode (TAB), choose the uv_0 map;
- drag this corner, change the window to UV editor;


- in UV editor enable sync, press B to activate box selection and select all parts of the garment;

- in 3d view press P and choose selection to separate the garment;
- select s4studio_mesh_1.001, switch to Modifiers tab, add Data transfer, choose s4studio_mesh_1 as Source object, set the rest like this, apply;

- select s4studio_mesh_1, disable Limit selection to visible, choose Vertex select, select all parts of the body that are covered by the garment, press Delete, choose Faces;

- select s4studio_mesh_1.001, Shift-select s4studio_mesh_1, press Ctrl J to join;
- put the garment's uv islands in the vacant places in the chest area;
- select everything, UVs - Export UV layout. Use this as a reference to edit textures
