Red Rabbit (2007)

3D animated short film

Last updated: 30 December 2021

Directed by Egmont Mayer

My role: Effects TD
Software used: Houdini, Python, XSI

I simulated a collapsing wall and ceiling in Houdini, and cached, exported, and imported the transformation channels for rendering the geometry in XSI.

I wrote a Houdini Digital Asset for shattering geometry based on curves drawn in the viewport, which I later reused on Walka and ColourBleed. In order to transfer the simulation to XSI, I wrote a Python script for converting baked simulation channels from Houdini into XSI actions, which could then be applied to the exported geometry.
