Looks like Reflection Probes are turned ON by default for Terrain Trees, even when Reflection Probes are turned OFF for the main tree. I can't find a setting to turn it OFF for Terrain Trees. Pics attached. 1. You can see Tree L (6), on the left, as main tree with Probes ON. Terrain Tree on the right side. 2. Turning Probes OFF for main tree 3. Going to refresh Terrain Trees - no result. No result from recreating Trees or creating entirely new Terrain as well. 4. Terrain settings. There's a way to turn ON and OFF probes for Terrain, but not for Trees. 5. Trying to place more Terrain Trees. Still getting Probes ON, except for the main tree.
