This is a rather trivial example: a chest is a model of two pieces (base and lid), and one of them (base) is not moving. So you have only one element (lid) moving in only one direction (rotating).
A thing I didn’t mentioned here is that you need import/export plugin for Blender. Literally falling asleep now, so try searching Discourse for it.
Also, voxelpirate has a mega useful video tutorial on youtube about animating SH models.
PS. Assuming you don’t have any pro-tools like Maya and want to try with free ones (Magica, Blender, VoxelShop).
