how do you make transparent clothing? {SOLVED}

Please follow this tutorial by UN: sims4studio.com/thread/1469/tutorial-create-transparent-skirt

make sure your blender file have exactly same amount of mesh groups as the original mesh. and also make sure your mesh groups have the same cut numbers as the original mesh. For example, the original mesh has 3 groups:
's4studio_mesh_1', cut number '0000'
's4studio_mesh_2', cut number '0001'
's4studio_mesh_3', cut number '0002'

your mesh should have the same mesh groups and cut numbers.
's4studio_mesh_1', cut number '0000'
's4studio_mesh_2', cut number '0001'
's4studio_mesh_3', cut number '0002'

nothing less. otherwise your mesh won't show up correctly.

please share your blender file and package file so i can take a look.

You don't need to duplicate the mesh in s4s. UN did that in his tutorial because he had 4 mesh groups in the blender file: 3 of them were the sim legs and 1 was the skirt. And in the package file there were only 3. So he had to duplicate one geometry in the warehouse tab and assign it to a new cut number so that s4s can read his 4th mesh group in the blender file.

The thing is the amount of mesh group doesn't matter. He had 4, you had 3. The content inside each mesh group doesn't matter either. As long as your blender file has the same amount of mesh groups as the package file, s4s is able to read your meshes. To make transparent clothes, you need at least 2 groups. You need to separate the non-transparent part and transparent part into different mesh groups. The most important part of making transparent clothes is to change the shader of the transparent mesh to be 'simglass'.

In your case, you already separated the legs and the skirt, which is good. You can just skip section 'B_Fix the package to read the new mesh' in the tutorial and jump to 'Optional: Create the inner part of the skirt, a border and fix the clipping problem Clipping'.

Also, you can delete the geometry you duplicated earlier.

SLYD, you said earlier that it has to have the same cuts as the original mesh. but how do i make one from scratch? i tried it, but the objects under certain cuts disappears
