I'm displaying some items in the "billboard" mode: https://www.babylonjs-playground.com/index.html#20K47P#1 The items would need to maintain the same color (or change it just a bit with the camera rotations). I believe it must be very simple to do, but, still bein a novice, I do not know how ....

This is a math question, or maybe a question for someone who understands how billboard modes work under the hood. Given a long thin mesh with a texture of a chain, how can I position it so it looks like a chain stretches between two arbitrary positions? Here is a playground that shows sort of what I'm shooting for (until you rotate the camera, anyway). Just imagine the mesh in the middle has a texture on it like a chain or a rope. The main point is to have the "chain" mesh appear to stretch from one position to the other, while keeping its planar surface facing the camera (so that it doesn't get thin and disappear depending on the viewing angle). My instinct was this might be possible with some combination of rotation and billboard modes. If not, I guess it will be necessary to take the camera's position into account? Or if there's a simpler way to achieve what I want, that'd be great. Thanks!
