We just open-sourced Crucible. Cook Houdini HDAs lazily at Karma render time. Just a single USD prim pointing at your HDA. Karma pulls, Crucible cooks, mesh appears. MIT licensed. Built for production.
Is it possible to use it for multistep deformation blur?
That's our biggest issue when creating Custom Husk Procedurals at the moment. Having to transfer velocity attribute from another prim. And being limited velocity/acceleration blur.
