Create a falling tree

I converted Japanese to English with translation software.

1) There is a layer of tree.
2) It is divided into an upper layer and a lower layer.
3) Tag the lower layer with "Collision".
4) Add "Dynamic" to the upper layer. It will be automatically tagged as "Collision".

5) Create a new scene.
6) If the start of the collision parameter of physical properties is "immediate", the tree will fall.
7) Normally, you can control the timing by setting it to "immediately" when you press "1" on the keyboard, "at the time of trigger".
