The update includes to bug fixes:
- Fix bug with MeshBakerFast texture packer where textures could be copied to atlas upside down on some platforms.
- This fixes issue where meshes baked in the editor cannot be modified at runtime. Added code to delete runtime created meshes when switching scenes.
The update also changes how Mesh Baker serializes references to game objects. Instead of using Instance ID a reference to a game object is used internally. This change fixes issues baking meshes at runtime, then updating the combined mesh later.
