I am attempting to update a lines object returned by
MeshBuilder.CreateLines with both
instance set. This works fine if the number of points stays the same. If I attempt to insert more points though, everything falls apart. The new points are not taken into account at all.
It’s easy to reproduce: https://www.babylonjs-playground.com/#165IV6#2361
I inserted a second loop from line 42 to line 46 and it has absolutely no effect. It’s like the object stops processing points once it has reached the quantity it’s “accustomed to”.
I have to dispose the old mesh and create a new one ATM, which is pretty slow compared to the update (although bearable for my use case). Is this a bug or just a “working-as-designed” limitation? edit: and if so, why not just check the length of the array and regenerate the mesh only if it differs?
Thanks in advance!
