I've been having fun modeling anthropomorphic skulls for halloween lately, and I thought I'd share the basics of my process.Why skulls? Because it's easier to make a realistic anthro character/model going UP from a skull than to model them based on soft tissue (skin, cartilage) going down. It's also a great way to learn anatomy!

Please do note that is is an extremelly rough guide to, ahem, genetic splicing.There are many aspects of how to combine the two models, which aspects of each to keep, etc- you can make your own decisions. This instructable is to help get you on your way, or to make a little fun thing. Don't hunt me down with the finer points of anthro canon. Thanks.

I do a lot of additional modeling to add dimension and character, but for this Instructable I will try to help you go from 2 models (one animal and one human) to one completed anthropomorphic model with as few steps as possible and with as minimal sculpting as possible. That being said, go nuts! Meshmixer is fun. See what you can add and change.

I HIGHLY recommend that you watch at least the first few videos of 'Meshmixer 101' on YouTube. There are many quick keys and controls that will make this a much easier process.

Things you'll need for this Instructable:

Meshmixer (available from Autodesk for Mac and PC)

2 models of skulls (one human, one animal)


Mouse (way better than trackpad) or better yet, Wacom tablet

3d printer

Step 1: Find Your Models

There are a few great resources for .stl files online. Human skulls are relatively easy to come by, but there's also lots of animals to choose from! Try googling 'free animal .stl' or 'free skull .stl' here are the sites I used:


will take you directly to the animals category on that site,


I used this lion skull:


and this human skull:

<p>Came out nicely!!</p>
<p>Wow, well done. I wonder how well this would work creating appliances in silicone merged with a 3D scan of an actor's face? Seems like makeup artists could eliminate a few steps.</p>
<p>Thanks! Well, the next steps with this (for me) is to do a mask form- so I'll let you know! I plan on doing the soft-tissue as it's own' model.</p>
<p>Super-cool!! If you want to make large-area manipulations, try selecting the area you want to move and using Soft Transform (under the Deform menu). This will smoothly blend in your change (you might need to tweak the Falloff distance)</p>
<p>The finished humanish-animalish skull is quite creepy. Nice!</p>
