Hello, I have a use case where I would want to - create a mesh (for example- Cube) remove a vertex on some event (say mouse click) reconstruct the mesh I am able to remove the vertex from the mesh's verdata but when I use Delaunay triangulation to find the new Indices, the mesh geometry gets distorted. Not sure what to do here? Any help is much appreciated.

Hello everybody :-) I'm trying to use ExtrudeShape for creating a building shape and am having trouble with the cap. I understand that the cap is not tessellated (triangulated) so it would be faster. But when I have concave angles in the shape, it doesn't look good. I also tried using Ribbon for the roof polygon somehow, but the tessellation doesn't happen here either of course. Here is my code: http://www.babylonjs-playground.com/#1KQZAF#0 I tried using PolygonMeshBuilder but the mesh is rotated the way I don't want it to and some walls keep dissapearing depending on the angle of view: http://www.babylonjs-playground.com/#SJLOW#1 I don't need the mesh to be updated so the speed of tessellation doesn't bother me much. What am I doing wrong? What can I do to have a tessellated building? Thanks :-)
