mmmh... currently the cap the computed from the model shape barycenter what is fast (especially when the mesh is dynamically morphed) but doesn't fit the needs for people just wanting a fixed mesh and more versatility in the cap management. This means I will have to implement something like a staticCap feature, a cap computed from a triangulation algo with some predictible positions, so uvs, if possible. For now,  the capping algo can't do this unfortunately. The best choices are eithe
