In the popular editing programs premultiplying a texture is not straightforward. For example, this is what you'd have to do to convert a non-multiplied image to premultiplied image in The GIMP:
At this stage, it is important to note two issues we've encountered specifically on Android:
Let's combine everything for an effect. We will create a very basic, simple and quick fire-burst effect, like the one you'll expect to see in the rocket's exhaust or an oil rig. Our fire will have three stages: Ignition, flame and smoke. The ignition happens at the base of the fire, and it's very bright -- it illuminates its surrounding and it's almost white in color. The flame is the fire after it's detached from the fuel, and is yellow-orange in color. It still provides some illumination, but not like the ignition. The last part is the smoke and soot -- It is grey or black and blocks what's behind it until it disappears.
Here are the three stages in our particle's lifecycle: (zoom set to 300%).
(Please note that for demonstration purpose I only listed the key frames in our particle's animation. These key frames should be interpolated to create smoother particle animation.)
