### Remarks

Normal mapping (or bump mapping) provides more surface detail with normal map textures to increase the visual fidelity. The default value for this variable is `true`.

To change this setting for a specific LOD, see [SpeedTreeImporter.enableBump](/engine/6000.7/script-reference/unityeditor/speedtreeimporter/enablebump.md) and [SpeedTreeImporter.enableSettingOverride](/engine/6000.7/script-reference/unityeditor/speedtreeimporter/enablesettingoverride.md).
