Maybe this is common knowledge, but i didnt realize til recently that whenever you're manipulating an object or a group of objects, when you do the right trigger rotate thing, you can press the left trigger also to fine tune it rather than snapping, which means you can make a takeoff or landing or whatever have any angle or tilt or position you want, instead of being stuck to the one takeoff angle and 2 landing angles
i'm making a really sick park with all kinds of weird transitions and hips and stuff.. i'll post it later if it's sick
