Trying to make a bodysuit and the pants overlap with shoes

Hi. There is probably something wrong with the region map, could you please share the package files

So for it to work as intended the mesh must be made of 3 meshgroups. No swimsuit for masc frame seems to be, so you'll need to make one

- clone ymBottom_UnderwearSexy, export all blends, open the first one;
- select top.001, shift-select s4studio_mesh_2 (in this order!), in 3d view press Ctrl J to join;
- switch to edit mode, select everything with A, remove doubles with Merge distance set to 0,0001;

- remove doubles for other two meshgroups;
- save, close, repeat the process for other 3 lods. You are meant to be joining the top with the meshgroup that connect to it, so pay attention to that and not the name of it;
- clone ymBody_TowelPlush, import all lods and textures there. No need to touch Sort layer

However, the torso is joined with the wrong part of the legs. Turns out s4s gives different names to meshgroups, so what was named s4studio_mesh_2 in my case is named s4studio_mesh_3 in yours. You must re-do this. The torso should be joined with the part that is connected to it, the groin+thighs.

Cloning is a process of creating a duplicate of the existing item. When you click on Create CAS stanalone or Create 3d mesh, that is cloning. Just embed all resources or use Create 3d mesh

The Mac version does not have create 3d mesh because by the time it was introduced these two features did the same thing.

Did you import all textures from the original package? Or did it not have shadow, spec, normal maps?
Import these blank textures of appropriate size
