I was trying on the feature of Soft Body made from Clones.
All I have to do is to set up a ground as a collider, set up a Cloner Object with Grid Array.
Afterwards, attach a Dynamics Body on the Cloner, turn the Collision ellement to All, and finally set the Soft Body to Made of Clones.
Yeah, it is that simple. :)
Although the same effect can be done on previous r11.5, the new r12 gives the capability to have different child clone of the Cloner Object to have a different Dynamics behaviour, because the tag is now can be applied to the Cloner children instead.
