you have control on what you want to grab. All you’ll have to do is enable the necessary custom trace channels (in documentation) on any mesh and it will grab. I set it off by default so you have more control over where you can and cannot grab when doing level design 
btw, I do have vine climbing/scrambling in the works right now. So you could use that when it’s ready although I didn’t plan for it to work on steep slopes… I might add that support a little later with an update
