Worm/Virus/Tentacle Generator HDA
This HDA that I created is originally for generating tentacle on the surface of geometry and for testing FEM system in Houdini - The tentacles follow the target object.
I realized that the tentacles model could be made as a digital asset.

The exact generated model, using a sphere as the base.
Operating Menu
There are 4 main sections for this tool.
First, this tool converts the model that you connect into VDB.
Second, you can select the Polyfill checkbox if the model was a unclosed geometry.
Third, you can decide how many tentacles that you want, which means how many points that you want to generate on the surface of the model. You can also randomize the positions of the points with the seed value and the relax value.
Last section is the shape of the tentacles, you can decide the length and the resample level, then modify the ramp for shaping the tentacles. You can make the peek of the tentacles very sharp, or look like round and curve, like the first image that I show you.
