How To Add A Stand
YOU MUST UNDERSTAND THIS BEFORE ADDING STANDS:
When you put mood mixer on the ground and look at it you'll see a large blue rectangle with transparent gray boxes set in it's surface.
Each of those gray boxes has an individual "contents" which holds the animations for that particular mood.
You can't see the individual contents right away when you select Mood Mixer in edit mode. What you'll see first is the contents of the large rectangle (it will have all your walk, swim and chat animations in it's contents).
To see the contents of each gray box, check the box for "Edit Linked Parts" in the edit panel -- the contents panel will go blank -- then choose which gray box to edit and drop the animations in.
One step harder than adding a walk but here goes: select a linked box to edit, dump your anims in, they're ready to use!
