Let’s take a look at some simple pflow coloring methods.

 

Here is standart pflow scene. After birth, wind force will drive particles around and Lock/Bond will let them to slide on sphere surface.

Particle age map

Particle age map added to diffuse and opacity channel. There is a nice shift between colors.

Important: for Particle Age to work, particles must have correct life span, best method is to add Delete operator in the same event as Material Dynamic×

Gradient ramp

Similar technique as previous, but colors are maked from gradient with mapped particle age map as source.

Multi materials

This time let’s assign multi/sub materials to particles. It can be done with material static, material dynamic, of material frequency operators. In our situation, we don’t need to make every single particle different, only different trails, so let assign material to root particles.

UVW mapping

Simple, planar mapping. Try with default noise map or more advanced gradient ramp with noise amount.

Distance

Fallof map have ability to blend colors (or maps) dependly on distance to any object.

 

There is also ability to map entire particle system as any other 3dsmax object. Check out Mapping Object operator.

 

In next part I will show some #box3 as well as krakatoa coloring techniques. Stay tuned…

    Thanks for sharing! I have a question though. For multisub material setup, how do you select the root particle for assigning the color? Thanks for your generous help.

      Hi, you don’t need to select anything, just add material operator to event01. Check out screenshot in this post.

    Interesting, I just put the material dynamic operator in the global node, and it worked just the same. Thanks for the reply.

    thank you very much, im very beginner for pflow, yet this tutorial helps me a lot to explore advance features.
    - i have a doubt, if you don’t mind.
    Fallof map have ability to blend colors dependly on distance to any object; i try move the teapot farther and nearer, but i didn’t get what it usage,.

    im sorry if its silly question :(

    Thanks for the tutorial! I always found particles fascinating, but I don’t yet know them well as I’m a 3D modeler, not a vfx artist, so the file provided was a great learning aid when I analysed it bit by bit.
    great looking website too, by the way!

    Hi Deko,

    First of all thanks so much for the tut and the max files, My question is on the particle side say if I have a more complex
    object than a sphere how do I make the particles stretch across the object and the spawn last longer.

    Thanks

      Hi James,
      of course you can choose different shape. Just pick your object in Position Object and Lock/Bond operators. And to make particles living longer, look at Delete operator.

    Hello, great tutorial, i’m a bit new to pflow. I’m working on a scene using two different objects sources emitting smoke of different colours. I however can’t figure out how to tell pflow to use the colour of the smoke for the particles. Can u help?

      Hi Rob,
      unfortunately, native pflow can’t read fumefx color data, but it’s possible with new Krakatoa or Stoke from Thinkbox software. In next tutorial I will show how to make it.
