Environment Spawner is a faster and easier alternative to prefab painters.
Create categories of prefabs, tweak a variety of settings and spawn the environment you want across multiple terrains at the click of a button.
Any buildings or other objects with a collider on your terrain can be avoided automatically.
You can create underwater categories for objects that should be spawned underwater and tweak the depth limit settings to limit how far underwater the objects are allowed to spawn.
Feel free to check the Documentation to get a better idea of the available settings to help you spawn the perfect environment for your terrain.
If you have any questions, I’ll happily answer them for you here.
