Procedural Hex Map - Catlike Coding

I am trying to get the Catlike Coding tutorials to run, for creating a Procedural Hex Map, but not having any luck.

In particular I have the latest version of Unity (2020) as well as Unity 2017.3.0f3 (the last tutorial was done with 2017.3.0p3...). I am importing the Unity package for the last tutorial into 2017 and 2020.

https://catlikecoding.com/unity/tutorials/hex-map/part-27/

Running that and I get a blue screen in 2D scene and 3D scene nothing but the horizon...no hex map.

Any clues?

Also, I don't see any assets in the store for creating procedural hex maps, but I think I would rather do this from scratch anyway...

 

If you want to do it from scratch I would start at Part 1 and work your way through rather than downloading the completed version. If something did change between 2017 and 2020 that breaks it you will then know exactly what it was.

EDIT:

Did you take a look at the troubleshooting at the bottom? Maybe related to:

That happens because the camera uses a custom Rotation axis. You need to add this axis. See part 5, Larger Maps for the details.
