S4 CAS Tools   (Views: 2,258 )

This is a full-purpose tool for creating CAS custom content for TS4. It’s specifically meant to work with Milkshape 3D and to get around the limitations of using MS3D for Sims 4 meshes, but many of the functions can be done with OBJ files which can be used by almost any meshing program.
