Hello, to get rid of the skybox you need to do following: Enviro Sky Instance -> Rendering Setup -> "Set Clear Camera Flags" off. Enviro Sky Instance -> Edit Profile -> "Sky" category -> "Skybox Mode" to "Custom Color". Goto your camera and set your clear flag to "Solid Color" for example. You may also want to remove the Skybox from your "Unity Lighting Settings" that may still be assigned. Now to change the clouds height you can have a look into the clouds quality settings and tweak the bottom and top height here. Do this for all quality profiles you want to use. I never worked with AR yet, so there maybe is more to do or tweak. Just contact me in a private message or join our discord (https://discord.gg/5c6kfW6) and we can have a detailed look into that.
