Nice result but running the web demo locally is way too complicated in 2024. You should make a exe version for sure! That said, I peeked the unity package and as an experienced Unity user, I disliked the easily avoidable compiler errors and the extra "Scene" folder. The way the project should be condensed is into a folder of its own, but short of that, you should at least adhere to the standard structure of the Unity base folder. Why have 'Scene' and 'Scenes'? The easily avoidable error: Assets\Editor\TerrainEditor.cs(529,26): error CS0104: 'Cache' is an ambiguous reference between 'CoherentNoise.Generation.Cache' and 'UnityEngine.Cache'
This error could simply be a result of using a newer version of Unity than the one you used, but I saw no instructions about which version to use and defaulted to the 2021 version. I fixed the error by just replacing the 'Cache' instances in that script with "CoherentNoise.Generation.Cache", but turns out this project also has some dependencies I missed and cannot figure out what's missing.
