 If you need to perform per-object adjustments to mesh LOD, you can adjust how
 aggressive LOD transitions should be by adjusting the **LOD Bias** property on
-any node that inherits from GeometryInstance3D. Positive values will make LOD
-transitions happen sooner than usual (resulting in lower quality but higher
-performance). Negative values will make LOD transitions happen earlier than
-usual (resulting in higher quality but lower performance).

 Additionally, ReflectionProbe nodes have their own **Mesh LOD Threshold** property
 that can be adjusted to improve rendering performance when the reflection probe
