How did you use Houdini to make your game?
As always, Houdini was used as a content creation powerhouse. The platforms were generated on the fly from simple block-out meshes, the walls of Limbo were drawn from curves (as were the hanging cables) and just about anything that wasn't a one-off hero asset was done in Houdini. By building out and refining the tools it was easy to put together the final areas of the game much faster than any other possible way.

Houdini also helped in the game's FX as well. Multiple meshes were generated in Houdini and exported to be used in particle effects or as other visual elements.

A couple of meshes were built fully in Houdini and exported like the jar at the end. Houdini's cloth sim was used to create all the blocking fabric "doors" you encounter. One item, the sharp needle you collect, was remeshed from a sculpt inside Houdini as well.

It still feels like cheating sometimes when I can build out a whole level with custom-looking meshes in a matter of seconds.
