14 | Basics Nodes Reference > Level of Detail group node Blocking For example, if you translate a cluster to deform a geometry, then set the Node State of the cluster node to HasNoEffect, the geometry appears undeformed, as though the translation had not occurred. To view the effect, change the Node State back to Normal. Temporarily hides the node and does not display the results of any input (input evaluations) to the node. This can speed the redraw. It is also useful when you have complex scenes and want to edit only one aspect of a node. Blocked nodes do not render. For example, if you have a complex revolved surface and want to edit the curve, but don't want to wait while the curve redraws, select Blocking and edit the curve. To display the modified revolved surface, reset the Node State to Normal. Notes • The "HasNoEffect" state has a different meaning for each node type. Some node types do not implement the state, in which case the state acts just like "Normal". • The "Waiting" node states are used internally by Maya to keep track of nodes that are waiting for a view update in the Hypergraph. You should not normally set nodes to a "Waiting" state. Level of Detail group node In the Level of Detail (LOD) group's Attribute Editor, you can modify the following LOD Attributes: Min Max Distance If the minMaxDistance is turned off (default) there is no change in behavior. If it is turned on, the minDistance and maxDistance attributes define the visibility range for the object. Min Distance The minimum distance at which the group is displayed. Max Distance The maximum distance at which the group is displayed. Changing the Threshold distances You can change the distances at which the levels are switched using the Channel Box. To change a Threshold distance 1 Select the level of detail group node in the Hypergraph. Its level of detail attributes are displayed in the Channel Box. Basics 451
