Particle Smoke

General

Requirement: This tutorial is based on the Particles Fire tutorial. Alternative [Particleflame|Particles Flames]] can be used.

User level: Normal

Blender version: 2.43

Results: Smoke and Fire

The flame particle will be copied and modified to simulate smoke via an alpha texture.

Preparation

• Follow the Particle fire or Particle flame tutorial.
• Create the texture with any paint program. Name it Particle_alpha.tga. It requires an alpha channel. You can use following channels to compose the texture:

The RGB map is plain black.

The Alpha map is visible in the centre fading out to the border.

• As black smoke is difficult to see on black background go to shading<F5> -> world buttons and change the background color to a medium color (not white).

The Particle

• In layer two make a copy of Particle_fire name it Particle_smoke
• Move Particle_smoke to layer three <m> or move it away from Particle_fire
• Display the IPO curve Editor and make the IPO curve single user copy. This ensures we have a separate IPO curve for smoke and fire.

• The logic can remain as it already is.
• Rename the IPO curve to Particle_smoke.
• Remove the IPO curves ColR, ColG, ColB.
• Change the IPO curves ScaleY, ScaleZ and add ColA as shown below:

• Use this guide to set the control points:

IPO keys

Channel	1	2
ScaleY	(0.0,0.6)	(30.0,2.0)
ScaleZ	(0.0,0.6)	(30.0,2.0)
ColA	(0.0,0.0)	(30.0,0.0)
