As apart of the Uni SA Graduate Certificate in FX and Lighting at Rising Sun Pictures, each student is tasked with creating an FX project. The project I chose was a doughnut being shot at a wall.

The creative brief I gave myself was a doughnut being shot at a wall. Created in Houdini, this project uses Vellum and Particles to show our tasty friend being shot at a wall and meeting it's crumbly demise.

The Breakdown

The doughnut was modeled in Houdini and fractured using a boolean fracture to create a specific break that was similar to reference. The sugar was created using a particle system, and that same particle system was used to create a dough chunk spray. The doughnut ammo crate was modeled in Maya and textured in Substance Painter.


Unfortunately, there aren't many doughnut smashing videos on the internet - therefore finding reference was very difficult. This meant I had to make a trip to the supermarket and buy some unwilling doughnuts to be filmed being hurled at the side of my house.

Early Concepts

Initially I had used vellum grains for the base of my doughnut, but found that it resembled too much of a ball of sand rather than the humble doughnut.

This tear test had the correct look for the inside of the doughnut, but as previously mentioned - still resembled a ball of sand.

Next Steps

I'm going to continue this project and create the jam spraying out in either a FLIP or POP fluid simulation!
