As in the description the parent and child render/disappear at the same time when camera distance change.
The issue is now closed but the problem still exists. I have followed all the instructions given by likangning93, changed all the “ADD” to “REPLACE” in all directories. Not working.
Looks like the issue has been re-opened, and it might be that your tileset isn’t valid. The spec says that when a tile points to an external tileset it cannot have children. See the discussion here for more details:
Feel free to follow up there or in this thread if that doesn’t make sense.
