A believable skeleton is full of complexities that cause it to be a majorly time consuming model to produce. Through the process of producing this model, I can assure you that all of the specific bone shapes, lengths, and structures - not to mention the UVs, take a lot of time to figure out. Now you can save the time that I have spent with this product!
This Skeleton is fully set up with a rig that is intuitive and easy to use. If you choose not to use the rig, the skeleton can still be effectively manipulated through its hierarchy in the included un-rigged version. All of the textures have been created at 2048x2048 resolution but 1024 versions have been included if necessary. All of these are also easily editable should you wish to change the surface look of the bones. The sutures of the skull have been slightly exaggerated to read more effectively in animation and different lighting conditions.
Whatever your needs - I am confident this model will be able to serve you as well as it has for me.
