Vault and the Nexus because that was what I had been commissioned to do.
A number of people expressed interest in the single-headed model, so I rigged the snake, adapted the hydra animations for it, and uploaded it to the Nexus. I tried to upload it to the Vault nearly twelve hours earlier, but as of this writing, its entry is still pending approval. As can be seen in the picture below, I provided both a non-tintable (left) and tintable model.
One of the good things about this model is that, if you need a smaller snake, you'll find that it actually "scales" well.
Like a serpent biting its own tail, my project has come full circle at last. It is such a relief to declare this Herculean effort over. I can now move on to making other models – nothing with scales please. I'm so sick of them.
