Back in 2024 when GLTF mesh project was getting looked-into by dear Runitai, there was a lot of chat about mesh cloth and the impracticalities and learned lessons about MD-to-Sansar, and I asked the following: Could the viewer possible simulate a collision shape made of hulls along bones, scaled by avatar deformer weights? Like a kind of viewer-side auto-generated rough collision skellie that mesh could "opt in" to being deformed by? Would get rid of storing all the data in the asset, provide flexi-like basic movement to a pre-draped clothing item Runitai Linden replied with: flexi mesh is practical auto-rig a mesh to a flexi prim at runtime, animate mesh with the flexi anim see also physics bones you could rig to So! At the time, Runitai was working on GLTF and I didn't bother with a feature request bc he was on top of it. But since he's gone on to other things...I realized I ought to capture this in a request, and put his winsdom on how it'd be done in there!
