Mesh being weird in CAS

Hi cshell067, this is happening because the skirt part of your garment is in the wrong mesh group and it is replacing an EA mesh group that has no slot ray data. Slot ray data is what the game uses to tell where to put the Sim's arms in relation to the garment the slot ray data pertains to.

The original item you cloned has the entire dress, top and bottom, in mesh group 5. This mesh group is the one that has all the slot ray data needed to tell where the Sim's arms and hands should be when wearing the dress. You have the top part of the garment in mesh group 5 but the skirt part in mesh group 1. Mesh group 1 originally was a small plane in the sleeve area and it has no slot ray data.

I think you could fix this by making mesh group 1 a single plane that you bury inside the Sim where it will not show and bringing the skirt part of the dress back into mesh group 5.

Also, if you run into Creator Help type questions like this you are likelier to get a timely answer if you post them in the Creator Help section rather than in the Discussion and Feedback section. This section is not really where those of us who answer Creator Help questions look for Creator Help questions that need answering.
