MergeMeshes and subdivideWithSubMeshes

Questions
1

Hi everyone,

I was trying to understand SubMeshes and managed to understand them less now… :grin:

Please check this out: Babylon.js Playground

All scene stats say there still is two meshes, bounding box, too.

However, obviously, there is rendered only one mesh (or two on top of each other). What I get even less are the data of the two submeshes: vert0: 0, vertCount: 4 for both. Should the second one not start at 4? Similar for indicies.

So is this all expected behaviour I do ont understand, or is there a bug?

Best wishes
Joe
