Maya Hair Simulation with imported collision geometry

Is there a tutorial or workflow not using Hait Template to setup maya FBX exported splines to setup to simulate in Lens Studio with it's Hair Simulation and collision system?

I have been looking into the documentation for Hair and Maya and found some basic documentation here: https://docs.snap.com/lens-studio/references/guides/lens-features/tracking/face/face-effects/hair-simulation#hair-component

This seems to show how to do this with template but I am looking at doing some simple collisions with imported, enveloped geometry and attaching splines.

In Unreal this workflow would be similar to https://docs.unrealengine.com/4.27/en-US/WorkingWithContent/Hair/XgenGuidelines/

Any time, comments, or suggestion are much appreciated.

Follow up: If anyone is interested, I built some custom hair attachments in Lens and attached them with per bone collision object colliders, a baked skeleton join along surface in maya via FBX, then parented each collider and hair object in lens for desired effect. I started with the hair template and built from there. It's a cheat since I cannot paint per hair attribute physics not deforming hair base, but it worked alright and made some interesting results.

    Hey David, I'm interested in doing the same thing and was wondering if you could run me through a little bit more of the process you used. Thanks
