The camera kept its height (only ZR and ZL changed it) and rose whenever the closest surface in the lower part of the view came within about three metres, so flying up to a character, a rock or a wall sent it upwards. It now moves where it looks and nothing stops it, the ground included. Ground avoidance is a checkbox in the debug menu's free camera section. With it on, the nine view distances read back from the lower view become points of the scene (from the view's angles and the camera's pitch), and only a column whose lowest surface rises by less than about 30 degrees counts as ground: the camera goes no lower than a metre above it. Steeper things, objects and walls, are left alone. The read-back runs only while the switch is on. Tested on a village save, 4 m/s forward for 5 s and then ZL for 4 s: with avoidance off the camera ended 17.4 m lower, through the floor; with it on it ended 0.7 m lower and held there. Flown at Link with the first version of the ground test, its height did not change. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
