Dev notes

• How to turn off depth fog (say, for scene editing purposes):

  Navigate to Assets/Rendering/Fallback URP Renderer, find the bottom-most renderer feature, which should has a title of Depth Fog (Full Screen Pass Renderer Feature), turn it off, and the fog will be gone.

  Don't forget to turn it back on before building/publishing!

• How to change the terrain materials to the gray box material:

  Open the "Terrain Toolbox" window (Window/Terrain/Terrain Toolbox), switch to the "Terrain Settings" panel, under the "Basic Settings", tick the checkbox before the title and find the "Material" slot in it, select the "Gray Box - Default" material, and then click the "Apply to All Terrain(s) in Scene" button at the bottom.

  For some unknown reasons, the terrain materials will automatically switch back to the normal material indefinitely.
