Ever tried positioning a car asset on uneven ground? Randomly stacking up a pile of toys in a children’s room? Just using translate and rotate tools, it’s not a quick or easy proposition! That’s why we’ve added a new tool that enables you to use collision and gravity simulations in real-time inside the viewport for object placement. Check out how the Physics-based asset placement works in Twinmotion 2022.2 in this new tutorial.
