Without optimizations of the vertices buffer, correct, it’s a 1T loop. But we can work on faces and normals so that reduces it by a factor of 3. We can octree it further as well spatially but…

There’s a really clever trick Unreal does with their decimation algorithm to produce collision shapes if you need to. I believe it requires a bake step (pre-compute offline).

I’d be fine with a bake step for this.
