Topology and Face Muscles

Restored Fresco of “Ecce Homo” (2012) [1]

This picture sums up how I’ve been feeling this semester. I made a lot of progress on the topology and the initial rig set up, but it took a while.

I had a number of topology issues that I wanted to fix.

The deformation of the brow and the way the topology distribution changed in the cheek area were an issue for me.

A summary of the topology issues I wanted to fix.

When I modeled this character for another class I had used my former model as a base for it. I didn’t end up using that topology however, because I had issues in the eye and cheek area, just like I pointed out above.

The topology for the character early on, using my old model.

The cheeks and eyebrows had issues where they wouldn’t quite deform enough for the model, when I thought it should. I know that not every model can share the same topology, but this character wasn’t too far away from a human.

Here is where I feel like the fresco restoration image.

Why?

The topology itself was better, but the shapes had been lost.

The current model and UVs.

I redid the eyelid, shaping out a crease and making it halfway closed for rigging. The cheeks are more evenly distributed and I re-defined some of the shapes.

Face Muscle Study and Joint Plan

I created this study of the main facial muscles and overlaid my joints on top of that.

Face Rig Setup

Since I was constantly editing and re-editing the character’s face, I often had to re-do the symmetry of the character. This messed up the UVs often. I got so annoyed that I wrote a script to flip the UVs automatically in the UV space I wanted.

I have to edit the UVs? Not again!

awwwwwyeah

My tiny script. I haven’t done vertical flip yet. I wanted to make a prompt that asked which axis, but I didn’t have the time.

Here is the latest version of the model, as well as a view of an LOD version.
