Group shot of the audience for tonight’s meetup 😁

A sim for the membrane and another sim for the strands. Here’s the strands! They are made using ‘hair constraints’, a vellum constraint preset included in Houdini by the geniuses at @sidefx

Tearing, pinning, bending and stretching? It’s Vellum Time! (tm)

Much of the variations in shading and scattering in the finished shot are simply from different thicknesses of these entities!

Passes for veins, tissue and membrane are all output from this same custom growth solver, each with different custom settings.

Here we’re seeing multiple generations (earlier gens are green, later are red) of curves being ‘grown’ from seed points placed by Nema. They seek open space and are ‘shy’ when they get near other curves or additional barriers (here, the white lines)

Next up: THE BLOOD DRUM 😮😮

See those curves in the ‘blood flower’? Several curves came from pre-viz and animation. Multiple copies were made and offset to get this final look. Then they were skinned with several different profiles; some blobby and some sleek.

Early tests on the blood tendrils were much more fluid, but evolved into a more sinew-like bundles of fibers
