Particle and Expression: Particle Example 8 : Realistic Cloud

You wouldn't see any small particle elements in this tutorial. This post will be about making realistic clouds using particle expression. This is for the sky environment that I made for Post Production Project.

1. Set the Dynamics menu set, select Fluid Effects - Create 3D container - Option box.
Set the following options, Apply.

Resolution X, Y, Z : 50, 5, 50
Size X, Y, Z : 50, 5, 50

2. Go to Attribute Editor - Contents Method.

   Density : Off(zero)
   Velocity : Off(zero)
   Temperatur : Off(zero)

3. Scroll down and set the values, inputs and colours as below.

4. Check Texture Incandescence and set values as below.

View from below

5. To animate the clouds, Go to the Texture attribute under attribute editor.
     Right mouse button click on the Z axis of Texture Origin, select Create New Expression.
   Type in

     fluidShape1.textureOriginZ = time*0.2;

6. Playback the animation.

7. Play around with implode. As value of implode increases, clouds seem to collide in the middle. Maybe they can be used as explosion.
