Is it possible to still get information for Terrain Table Format on the Developer Hub? Plz 
The current link leads to the environments and terrain tools page with no information regarding the table format.
The table format link leads to the page below.
Thanks for this report! I’ve just logged it in our backlog, and we’ll get to it as soon as we can.
