Hi

What will be a good method to extract single sided geometry?

Eg. I wanted to sim the bag straps. The bag strap is double sided geometry. Want to create a low res single mesh for sim and later point deform the hi res bag strap.

I am looking for a method apart from eyeballing and selecting the faces.

If possible, is there also any way to generate the low res single side in the middle/ inside of the hi res geom rather than using its outer surface?

Thanks.

If the topology and point positions on both sides matches then I'd just Ray then Fuse.

If they don't match then I suppose it's not a trivial task...

It highly depends in your geo, hard to generalize

If it was done by simple extrude you may be able to extract polys fully surrounded by first half of points as a base and blend half way towards thr second half of points

In other cases you may find UV space useful as UVs may already be unwarped separately for both sides or on the other hand they may overlap which on its own can also help to separate front and back

For simple non-looping straps you can also reconstruct the flow from procedurally finding one of the caps and expand from there

In any case as mentioned depends on your geo
