Several months ago I supervised a project called Speak and May the Plague Take You. This short film required some surrealistic imagery of giant clocks smashing into the ground, including an hourglass. After wrapping the project, I wrote this technical breakdown because I tend to forget everything. Since glass shattering is a somewhat common effect but not necessarily simple to achieve, I hope this breakdown will help other Houdini artists grasp the fundamentals and maybe save some time.
The hourglass shattering effect required a lot of exploration in Houdini DOP’s. The sidefx glass of water shattering tutorial (I hesitate to call it a tutorial) as well as the example files for the voronoi fracture OTL were helpful in giving me a starting point to build my effect.
