multiple root joints

[Anonymous]

Is there an easy way to determine if a rigged model has more then one root joint? I'm working on a model, that i'm trying to import into Unreal and it claims that it can't claiming there is more then one root joint. I have looked over the model's rig in Maya and there doesn't seem to be any sign that the character has multiple root joints. is there a trick, tool, and/or shortcut to figuring this out or what else would be my solution(s) for this issue?

A brutal way:

1 Select>Hierarchy;

2 Display>Show>Show selection (let's hope that no visibility channels are locked and no display layers are off);

3 In perspView panel menu Show>None, Show>Joints;

4 If joints are too small/big go for Display>Animation>JointSize...

Now it should be obvious that root joints are those with no incoming spikes from other joints. Once you have determined how many there are, you can make one überRoot. The trickiest part is to gather those minor roots under it without ruining the rig's functionality.
