More defined convexHull using tolerance


I am looking for a little advice on the convexHull Geometry class, i am trying to use it to recreate the parts of a glb model, preserving all necissary outer positions of the BufferGeometries.

The convexHull's that are created reduce each part to it’s most outer primitive shape, preserving little to no detail on the majority of parts, even when changing the value of convexHull.tolerance

this older topic describes using alphaShape to achieve what i would be looking for but seems to be a dead thread.

does anyone know how i would either modify the convexHull class to tweak its threshold parameters or a way to achieve a slightly more refined hull in another way?

any help would be greatly appreciated!!

thank you
