Within the Render Queue Window, Under Output Module Type, select Alpha Only, see image below: Within the Output Module Settings Window ensure that you set Post Render Options to Import and that you select Photoshop Sequence as the output Format, see the following image: Set the name of the file to 'Guide4SelectionMaps.psd' and render away. Press the key combination, ALT+CTRL+S to render out a single frame.
As for changing the scale for a particle based on its lifespan, just use the Persistent property with a full-on white mapper and have the Affects property be such that scale increases with time. It covers the use of different images for each particle. Since a Selection Map only reads grayscale values, we'll only need to render the Alpha Channel of the Composition Window. For a newbie, take a look, instead, at my COW tutorial on Particle PLayland. Your composition Window should look identical to the image below: Let's render a frame from our Composition Window which we will then use as a guide as we create a grayscale image to be used with the Property Mapper options. Set Time Offset to 0 as this is the fastest setting. Add Effect>Blur and Sharpen>Fast Blur to Adjustment layer 1.To speed up our workflow, let's set the Time Offset Type to Absolute as this renders the fastest amongst the four options that we have. Turn off Visibility for Wind and set its in point to:5. Its also really useful if youre going to end up duplicating the same particle system several times as all you need to do is perfect 1. If you don't, render times just might drive you insane. The playground has a particle editor that makes everything a lot easier I tested out all of my particle systems in the playground before bringing them into the game and figuring positioning and making minor adjustments. Note: If you plan to test your mask and do a lot of previews set the Radius of New Particles to a higher number and move the hold keyframe to frame 2. Now set a keyframe for Radius of New Particles at 0 and another at:5 value 0.
