Since landscape doesn’t work under SM5, how should I build a hill with a house on it without the landscape sculpting tool in Unreal Engine?
Don’t use landscape. You shouldn’t anyway.
What can i use then?
You will need to switch back to sm6 to do landscape editing for sm5/Vulkan. It’s a bit of a pain but that’s the current workflow.
The landscape will work fine in sm5, just can’t edit using that shader model.
Meshes!? was that a real question?
