Hi,
You just spent 2 videos going over the intricacies of getting a single ball to fall and bounce down a pair of ramps. Â I was expecting a starting blender file that corresponded to those videos. Â But instead we get to tackle something a lot more complex. Â Why not give us the complex_obstacle_drop_1-ball-START.blend file, too? Â It's not in the downloadable zip file.
