Hi @Runixcoin
Almost there!
Looks like you have some flipped surface normals on the helm. If you are using Blender, you can go into edit mode, face selection mode, tap ‘A’ for all face, goto the menu top left of the viewport and goto Mesh > Normals > Recalculate Outside.
Then i’d double check the results;
You can probably get away with ‘hiding’ the ‘Head’ geometry too based on the encompassing design.
Look forward to your update!
