How can I create parameters that have 2 axis?

Bonzomi

The image above is from a demo video and I saw that one of the parameters have 9 points and formed somewhat of a box. This means that he can manipulate that parameter in more than just two directions, I have downloaded the Miku model and it doesn't show as such, instead there were 3 separate parameters for each axis.

Hi Bonzomi,

Try and click left area of the parameter (shown in blue in attached image). This will combine the parameter and and one right below it. This will enable you to make the model face towards four corners that are synthesized (e.g. synthesis of Angle X and Angle Y)

If you are working on a new model from scratch and trying to deform the model to face towards corners, you can learn how to use the auto corner synthesis tool here. This is a pretty powerful tool:
