Sky Master ULTIMATE can be setup directly from drag of a prefab in the scene, the only major step needed after that is the setup of the actual terrain.
This is done by erasing my sample terrains and setup the terrain in "terrain" section in the configurator, by extending the Unity terrains list, adding the terrain and press on "Setup Unity terrains" button.
The "Add snow material" must be checked or unchecked before the setup and if checked will apply Sky Master terrain material to the terrain (for gradual snow growth)
This material works best when a bump map is also assigned to the terrain splat maps.
The WATER object that holds the water can be moved up or down freely to match the desired water level.
The prefab uses the Volume particle clouds by default, in the video i showcase how to remove those clouds (cloud referneces in Sky Master Manager script) and enable the new in v3.4 shader based volume clouds (and bit of tweaking to get the look desired, plus showcase the shadow layer "Clouds (108) which can be turned off or on if shadows are needed - on by default -)
The initial land coloration is defined in SkyMasterManager, per season, in the video i showcase how to regulate the color for the (default) Spring season.
From video start up to 2:27 time, the prefab insertion in the scene and the user terrain setup are showcased, from 2:28 - 3:43 is the terrain shader and terrain start color tweaking (start color is given in Spring Terrain color variable in SkyMasterManager, spring is the default season) and from 3:44 - end is the removal of particle volume clouds and addition of the new in v3.4 shader volume clouds option and their parameters tweaking.
