When the VTuber laughs, you see the throat deform. When the game character sighs, the shoulders fall on a cubic bezier curve. There is no physics engine in the real world; there is only the illusion of weight.
I just discovered "Drawing Order." For three days, her left arm was rendering behind her torso. She looked like a horror movie victim. I fixed it. Now her hand clips through her hip.
The most impressive feat is the pseudo-3D turn. When a character looks left to right, true 3D would render a new profile. Live2D cheats elegantly. It scales the far eye down, shifts the nose across the face, and rotates the ears. It is a topological illusion, a carefully constructed lie that your brain accepts because it preserves the integrity of the original drawing. The character never looks "off-model" because the model is the art. live2d cubism
We do not watch the mesh. We watch the eyes. And if the rigger has done their job, we forget that we are looking at a collection of warped triangles. For a moment, we believe in the geometry of a soul. Day 14 of Rigging
You have spent three hours cutting a strand of hair into seventeen separate polygons. You have assigned a deformer to a nostril. You have told the software that when the head turns 30 degrees to the left, the shadow under the chin should warp by 0.4. When the VTuber laughs, you see the throat deform
I was a fool.

The manual says: "Place the pivot at the base of the lash." I have tried seventeen times.
