I have created a body mesh for my character in the first layer. The hands of my character are made in the second layer. The problem is now that if i select both layers i only can modify 1 mesh and not both meshes on the same time.
Because they are two different Objects and only one object can be in Active at one time. You can Join them with Ctrl-J (Shft-RMB the Body last if you want it to remain the OBject Data) but then they’ll both be on the same Layer.
