Ladders could be a good idea they would of helped me out a lot esp with building up to the islands in the sky

Maybe there is some way to integrate the natural ladder look as a placed cyube as opposed to a movable/scaleable object but yet created with the same crafting technique as making a chair, etc? Maybe one rung per cyube so you can integrate grabbing onto it to go upwards? The seamless texture is the tricky part so the knots don't give off a pattern effect I'm guessing.
OR
The ladder can be a given defined object size that you can snap on top of each other for climbing?
