Good morning, i have sculpted a mountain in landscape mode in UE, and I sould like to create a cave. When i use the rease tool, it erases all the way up to the top of the mountain. i have searched around, but i keep getting the visibility tool, which is not what i want. Is there any way to do it?

Landscapes are only 2D so if you want a cave you have to make a hole in the landscape, there might be some plugin to make landscapes 3D but I’d recommend this video: https://www.youtube.com/live/W4k-64wYHKs
