My game are crashing (Accessory)

I'm not exactly sure if it was your blender file or package file that was broken somehow, or it could be both. Here's how I fixed it.

• Clone a new package. I cloned a pair of earrings.
• Export the mesh from the new package.
• Append your mesh 's4studio_mesh_1' from 01.blend in your attachment above.
• Select 's4studio_mesh_1' of the earrings and delete all vertices in edit mode.
• Select your mesh and the empty s4studio_mesh_1 mesh of the earrings and join two meshes into one.
• Save the blender file and import it to the earring package.
• Import your diffuse map and change category to hat.

I'd suggest you redo a weight transfer as your mesh doesn't move with the neck properly. There's some clipping from the screenshot below.

You can clone the top and head mesh under rig tree as a reference to transfer the weight. Here're the steps:
1. Open rig tree and click the arrow icons for top and head mesh to allow you select them.
2. Select head and press Shift+D to duplicate the mesh. It should create a mesh called 'head.001'. Do the same for the top mesh which creates 'top.001'.
3. Join head.001 and top.001.
4. Select your mesh and delete all vertex groups to ensure a clean transfer. I'm not sure if this step is necessary but I always do this.
5. Transfer weight from the joined mesh of head.001 and top.001 to your mesh by following this tutorial. sims4studio.com/thread/81/weight-transfer-blender

This should fix it.

Did you follow the exact steps? It should work if you did. What version of blender are you using?
