Hello everyone :wave: My goal is to convert a mesh’s 3D position (BABYLON.Vector3) into a 2D screen coordinate. Based on my research, the method BABYLON.Vector3.Project is the correct tool to use here. I am currently able to call BABYLON.Vector3.Project, however, the BABYLON.Vector3 that is return…

After further investigation, I have to come to understand that the NaN error is related to the scene not being ready + observable. At the time of my Vector3.Project call. The following code showcases a solution: scene.onReadyObservable.addOnce(() => { alert('hi'); var pos = BABYLON.Vector3…
