How to demolish object and create particle dust.

1.	Create a Cube, this will be the cube which will be demolished in runtime. 

2.	Set its name to "Brick", position to [0,7,0], rotation to [30, 0, 50] and scale to [2,1,1]

3.	Remove it's Box Collider because the Rigid component will add its own collider.

4.	Create another Cube, this will be a ground cube which will be used for collision.

5.	Set its name to "Ground", position to [0,0,0] and scale to [10,1,10]

6.	Add RayFire Rigid component to Brick.

7.	Set Rigid Initialization to At Start and Demolition type to Awake Precache.

8.	Start Play Mode. Brick will fall down and will be demolished by collision.

Now let's add some dust to this demolition simulation.

9.	Turn Off Play Mode.

10.	Select Brick and add RayFire Dust component. You can add several Dust components for different types of duif necessary.

11.	Enable On Demolition property because we want to create Dust particles for demolished fragments.

12.	Drag and drop dust_2_m.mat from “Assets\RayFire\Tutorial\Material\Dust” folder Dust Material property. 

You can define several materials with different dust textures for variety in the Dust Materials list under Dust Material property. 

13.	Start Play Mode. Brick will fall down and will be demolished by collision and a bunch of particle dust will be emitted.

14.	Turn Off Play Mode.

15.	Now let's make dust more noticeable.

16.	Select Brick and in the Dust component set Opacity to 0.4

17.	In the Emission group of properties set Size Min to 1 and Size Max to 3.

18.	Start Play Mode.
