Fantastic Beasts and Where to Find Them

Magizoologist Newt Scamander takes us back in the wizarding world of J.K. Rowling.

My first feature-film project, where I contributed as Generalist-TD doing lidar preparation and retopology, Houdini layout, lighting and rendering using Mantra on the "Obscurus" sequence. I furthermore supported the FX-team by developing a "cobblestone-road"- and "rooftop-snow"- HDA.

Screencapture of the cobblestone-road HDA.

The FX-Team was given the task to do destruction for serveral cobblestone-roads in multiple shots, but since the modeling department did create the roads as one subdivided-grid (and a displacement shader), the FX-TDs faced a lot of prep-work to build actual cobblestone-geometry that is suitabl for RBD-simulation. I took this as a chance to help by developing "the cobbler", a HDA that automatically converts a polygrid into a cobblestone-road consisting of individual cobblestones.

Later in production, we had the need to generate snow on rooftops and window sills for our 1926 New York City, and after successfully releasing "the cobbler", I was again given the chance to tackle this procedurally in Houdini. I created a HDA that takes building assets as input and generates points on every polygon facing upwards. Some of those points where then deleted to generate believable looking snow-patterns, either using procedural noises, manually painted areas or a combination of both. After that, spheres of random radius were copied onto those points, converted into a VDB, the buildings VDB got subtracted, and the resulting "snow" was meshed, polyreduced to one's needs and exported as alembic.
