Create the multi-chain solver

By default, the multi-chain IK solver is not available.

To create the ikMCsolver node for your IK handle

In the Script Editor or Command Line, type the following MEL command:
```
	createNode ikMCsolver;
```
Press Enter on the number pad.
A new ikMCsolvern node appears in the dependency graph.

This solver is now available from the Joint Tool, the IK Handle Tool, and the Attribute Editor for any IK handle.
