Fragile

Created in Houdini 18.5.532. The hand is from Tommy test geometry with some judicious clipping while the sphere is a boolean object (for thickness). The constraint strength are painted using attribute paint to only allow cracking rather than fracturing.

In order to put this together with the least amount of rendering, the start frame is held and end extended using python scripts and ffmpeg (example file on my ffmpeg page).
