I noticed that there is a performance hit if you create a large number of instances of a plane with BILLBOARD_MODE_ALL. I’m assuming this is because instances have their own rotation, and Babylon must calculate the billboard rotation for all of the instances individually. Am I right? And if so, would it be possible to link the rotation so it only had to be calculated once? It doesn’t have to be pretty.
Or is there a better way to do this? I’m really just trying to manage lots of performant little sprites.
