8.1.2   If/Else Nodes

An If/Else node behaves differently from a regular node. A regular node is stepped though until the final valid modifier is evaluated, and then exits. An If/Else node is stepped through until a valid modifier is evaluated, and then the node is exited. Any subsequent sub-nodes are not evaluated.

If/Else nodes are marked with OR, , in the Selection Tree tab.

All conditions in an If/Else node must be contained in sub-nodes. If a node is defined as If/Else when it is created, only a sub-node may be added as a child. If a regular node is converted to an If/Else node, all conditions and modifiers outside sub-nodes are removed.

An example of how an If/Else node can be used may be found in Section 8.1.2.1.
