Hello @luboslenco On further investigation the issue is caused from ImportMesh.hx function finishImport which is scheduled in makeMesh to be called when calls to addMesh are finished. But when appending mesh only addMesh is called and finishimport is not scheduled or called at all. I see this is a performance tweak. If finishimport is merged into run as it was in the older versions it works again, but the performance gain is lost. Just to let you know where to look for this. Regards.

EDIT: Another solution I tested was to create a copy of addMesh, call it appendMesh and add iron.App.notifyOnInit(finishImport); to it. Then in the import functions where replaceExisting ? is tested to call appendMesh instead of addMesh.
