[Solved] Cannot Find Terrain Tools Toolbox (Terrain Tools Version 3.0.2-preview.3)

Hello all,
I'm new to both Unity and the Terrain Tools and am trying to open the Terrain Tools Toolbox in order to access more advanced features, especially exporting a heightmap to a PNG. I tried following the instructions in the manual (specific page linked below), but I don't see a Terrain tab under the Window tab in the top menu dropdown. Here's a picture of what I see:



I'm using Unity 2020.2.1f1 on a student license if that matters.
Cheers!

I tried this on 2020.3.11f1, it works properly, you may want to upgrade to it. And/or check if you have any errors in the console. Unity editor scripts don't compile properly if there are errors.

 

It must have been a script error; I resolved some script warnings and can now see it! Thank you!
