Create a copy of the project file
Open that file in Blender
You should see something like this:
Make sure the text editor is open
Make sure the “project_panel.py” script is selected in the text editor (1.)
Run the script (2.)
Running the script is only needed if blender is closed.
Press the ‘n’ key to open the editor’s sidebar if it’s not visible already.
Switch to the “ProjectSettings” tab on the sidebar (3.)
Make sure “Cycles” is the renderer
Turn on shaded view
Change the height and color textures in “Quick Settings”
Change other settings to taste
