How to detect if the streamed terrain is fully loaded with no LOD?

[nakata1609]

My game has a lot of terrain. Teleporting to a new terrain area sometimes takes a while to fully load the terrain with no LOD. Using RequestStreamingAreaAsync by ROBLOX appears to only check for the terrain collision loading, and perhaps a little bit of the terrain visual, but it doesn’t appear to check if the terrain LOD is gone or not.
