Change and apply settings

All the Terrain Settings in the wizard are identical to the Terrain Settings in the Inspector. See Terrain settings for more information about each setting.

However, in the Terrain Toolbox, settings are split into sections that you can enable or disable for better batch processing. When you apply changes in the Toolbox, Unity only updates the settings in enabled sections. Use the checkbox on each section's expander menu to enable or disable its group of settings.

Apply settings

Click Apply to Selected Terrain(s) to apply modified Terrain settings to selected Terrain, or click Apply to All Terrain(s) in Scene to apply those settings to all Terrain in the Scene.
