I'm looking to replicate the tangent stiffness option in the vellum attach to geometry constraint in the struts/glue constraints.
I have a plant that I want to keep from spinning around and tangent stiffness is exactly what I need, though the fact that I have to use an attach to geometry constraint means I need to package a collision geo with the sim setup which makes things way more complicated than simply constraining the leaves to the base of the plant. In the attach to geo constraint I'm using a tiny sphere at the base of the plant.
