Firstly, I'm not an animator! I put this together to test some new features in a beta of Toolbag 4, specifically new raytraced DOF, motion blur, new film grain and light gels. I had a basic bug model that I'd used previously for an animated pulsing filpbook texture in UE4 to use with a Niagara particle system. I added some extra detail and animated a really simple slither movement on a proxy low poly model, then layered up flex and cloth modifiers in 3DSMax to drive a more detailed model with skin wrap. Exported via Alembic at first, then FBX with bones as the file size exploded (I used the proxy animation mesh here with subdivision and displacement, also baked in Toolbag). Renders are straight out of Toolbag 4 latest beta.
